This paper presents an equivalent elastic model where each bi-linear spring is replaced by two equivalent elastic springs using an energy formulation and in the context of a post-buckling stability analysis. Such a model yields analytical solutions for the evaluation of the behaviour of steel joints under compressive forces, combined axial force and bending moment, which enables the reproduction of their full non-linear behaviour. The resulting formulation is applied to a simple beam-to-column welded connection initially loaded in pure compression. Subsequent loading of the joint in combined bending and various levels of axial force clearly shows the reduction in moment capacity.; http://www.sciencedirect.com/science/article/B6V28-42G0KSC-7/1/73c4c882afc2d4153316e1c9c34582b0

Dentro do conjunto de aspectos relacionados à elaboração de projetos em estruturas de aço e mistas de aço e concreto, destaca-se como de grande importância e interesse, para fins de dimensionamento, a consideração de elementos estruturais submetidos a temperaturas elevadas. Nesse sentido, o presente trabalho tem como objetivo principal propor a construção de modelos numéricos tridimensionais de pilares de aço pertencentes a sistemas estruturais correntes da construção civil, para análise em situação de incêndio, com vistas a simular numericamente a evolução dos níveis de temperatura ao longo do tempo com posterior acoplamento termoestrutural. Considera-se uma análise paramétrica com vista a variar as restrições axiais totais e parciais da barra, no referente aos deslocamentos axiais, contemplando desde a situação de extremidade livre até a restrição completa em resposta à consideração de apoio do tipo fixo, por exemplo. Os resultados numéricos são comparados a ensaios experimentais de outros autores, bem como com outros trabalhos numéricos já publicados. São obtidas respostas de deslocamentos axiais e laterais do modelo termoestrutural para diversas disposições de paredes em relação ao perfil...

Este trabalho visa a avaliar os efeitos dinâmicos em vigas esbeltas semi-infinitas com contato unilateral em apoio elástico sob flexão composta, e sua possível aplicação a dutos flexíveis de extração de petróleo offshore em configuração de catenária (Steel Catenary Risers) provocados por esforços de movimento da plataforma. O estudo se desenvolve com formulação de vigas semi-infinitas em duas dimensões (2D) com suporte unilateral elástico, considerando-se inicialmente apenas efeito de flexão, à qual se aplica o método das múltiplas escalas (MME) para obtenção dos modos de vibração, e posteriormente o método das variedades invariantes (MVI) para recuperação das relações modais entre as coordenadas generalizadas e as variáveis modais. Trata-se, a seguir, da formulação do problema com consideração da tração, tanto estática como dinâmica, e a projeção da equação de movimento completa segundo os modos obtidos no problema da flexão simples, para obtenção do modelo de ordem reduzida com efeito de tração, que permitiu estudar este último qualitativa e quantitativamente. A formulação inicial teve como ponto de partida a utilização de mudanças de variáveis que permitiu a transformação do problema de condições móveis em condições fixas de contorno...

Friction Stir Welding (FSW) joints of AISI 304 austenitic stainless steel (304 SS) using position controlled mode were investigated in order to understand and relate axial force behavior to welding quality. Joints were produced using two tools and four combinations of specific parameters. The results showed coherence between the axial force profiles and the low-magnification overviews of the welded joints. For defect-free joints, only a natural oscillation on axial force occurred after tool plunge. In contrast, abnormal or abrupt oscillations were directly associated with common welding defects, such as voids and nugget collapse.

1. When chemically skinned muscle fibres are activated by Ca2+ at an ionic strength of 170 mM, the spacing between the filaments has been shown to decrease with increasing force, suggesting that the cross-bridges can generate force not only in the axial but also in the radial direction. In the present study, radial force and radial stiffness of activated single skinned rabbit psoas fibres were studied by X-ray diffraction. The responses of the lattice spacing to changes in osmotic pressure by application of dextran T500, which is equivalent to force applied in the radial direction, was examined. The radial force generated by the attached cross-bridges was calculated, with the approximation that a negligible fraction of cross-bridges was attached in the relaxed muscle at the same ionic strength of 170 mM. 2. The active radial force was found to be a slightly non-linear function of lattice spacing, reaching zero at 34 nm. The radial force was compressive at lattice spacing greater than 34 nm and expansive at less than 34 nm. 3. The active axial force, on the other hand, was found to be much less affected by the application of dextran T500. Active axial force increased by 4% to a plateau at 4% dextran T500 and then decreased by 10% at 8% dextran T500. 4. While not under osmotic pressure...

The influence of geometry on the force and stiffness measured during muscle contraction at different sarcomere lengths is examined by using three specific models of muscle cross-bridge geometry which are based upon the double-hinge model of H. E. Huxley (Science [Wash. D.C.]. 1969, 164:1356-1366) extended to three dimensions. The force generated during muscle contraction depends upon the orientation of the individual cross-bridge force vectors and the distribution of the cross-bridges between various states. For the simplest models, in which filament separation has no effect upon cross-bridge distribution, it is shown that changes in force vectors accompanying changes in myofilament separation between sarcomere lengths 2.0 and 3.65 microgram in an intact frog skeletal muscle fiber have only a small effect upon axial force. The simplest models, therefore, produce a total axial force proportional to the overlap between the actin and myosin filaments and independent of filament separation. However, the analysis shows that it is possible to find assumptions that produce a cross-bridge model in which the axial force is not independent of filament spacing. It is also shown that for some modes of attachment of subfragment-1 (S1) to actin the azimuthal location of the actin site is important in determining the axial force. A mode of S1 attachment to actin similar to that deduced by Moore et al. (J. Mol. Biol....

The esophagus serves to transport food and fluid from the pharynx to the stomach. Manometry has been the “golden standard” for the diagnosis of esophageal motility diseases for many decades. Hence, esophageal function is normally evaluated by means of manometry even though it reflects the squeeze force (force in radial direction) whereas the bolus moves along the length of esophagus in a distal direction. Force measurements in the longitudinal (axial) direction provide a more direct measure of esophageal transport function. The technique used to record axial force has developed from external force transducers over in-vivo strain gauges of various sizes to electrical impedance based measurements. The amplitude and duration of the axial force has been shown to be as reliable as manometry. Normal, as well as abnormal, manometric recordings occur with normal bolus transit, which have been documented using imaging modalities such as radiography and scintigraphy. This inconsistency using manometry has also been documented by axial force recordings. This underlines the lack of information when diagnostics are based on manometry alone. Increasing the volume of a bag mounted on a probe with combined axial force and manometry recordings showed that axial force amplitude increased by 130% in contrast to an increase of 30% using manometry. Using axial force in combination with manometry provides a more complete picture of esophageal motility...

It is reported in the published literature that the resonant frequency of a silicon micromachined gyroscope decreases linearly with increasing temperature. However, when the axial force is considerable, the resonant frequency might increase as the temperature increases. The axial force is mainly induced by thermal stress due to the mismatch between the thermal expansion coefficients of the structure and substrate. In this paper, two types of micromachined suspended vibratory gyroscopes with slanted beams were proposed to evaluate the effect of the axial force. One type was suspended with a clamped-free (C-F) beam and the other one was suspended with a clamped-clamped (C-C) beam. Their drive modes are the bending of the slanted beam, and their sense modes are the torsion of the slanted beam. The relationships between the resonant frequencies of the two types were developed. The prototypes were packaged by vacuum under 0.1 mbar and an analytical solution for the axial force effect on the resonant frequency was obtained. The temperature dependent performances of the operated mode responses of the micromachined gyroscopes were measured. The experimental values of the temperature coefficients of resonant frequencies (TCF) due to axial force were 101.5 ppm/°C for the drive mode and 21.6 ppm/°C for the sense mode. The axial force has a great influence on the modal frequency of the micromachined gyroscopes suspended with a C-C beam...

Preclinical endurance testing of total knee replacements (TKRs) is performed using International Organization for Standardization (ISO) load and motion protocols. The standards are based on data from normal subjects and may not sufficiently mimic in vivo implant conditions. In this study, a mathematical model was used to calculate the axial force profile of 30 TKR patients with two current implant types, 22 with NexGen and eight with Miller-Galante II Cruciate-Retaining TKRs, and statistically compare the axial force specified by the ISO standard to the TKR patients. Significant differences were found between the axial forces of both groups of TKR patients and the ISO standard at local maxima and minima points in the first half of stance. The force impulse (area under the axial force curve, representing cumulative loading) was smaller for the ISO standard than the TKR patients, but only for those with NexGen implants. Waveform analysis using the coefficient of multiple correlation showed that the ISO and TKR patient axial force profiles were similar. The combined effect of ISO standard compressive load and motion differences from TKR patients could explain some of the differences between the wear scars on retrieved tibial components and those tested in total joint simulators.

Immature primary and stem cell-derived cardiomyocytes provide useful models for fundamental studies of heart development and cardiac disease, and offer potential for patient specific drug testing and differentiation protocols aimed at cardiac grafts. To assess their potential for augmenting heart function, and to gain insight into cardiac growth and disease, tissue engineers must quantify the contractile forces of these single cells. Currently, axial contractile forces of isolated adult heart cells can only be measured by two-point methods such as carbon fiber technique s, which cannot be applied to neonatal and stem cell-derived heart cells because they are more difficult to handle and lack a persistent shape. Here we present a novel axial technique for measuring the contractile forces of isolated immature cardiomyocytes. We overcome cell manipulation and patterning challenges by using a thermoresponsive sacrificial support layer in conjunction with arrays of widely separated elastomeric microposts. Our approach has the potential to be high-throughput, is functionally analogous to current gold-standard axial force assays for adult heart cells, and prescribes elongated cell shapes without protein patterning. Finally, we calibrate these force posts with piezoresistive cantilevers to dramatically reduce measurement error typical for soft polymer-based force assays. We report quantitative measurements of peak contractile forces up to 146 nN with post stiffness standard error (26 nN) far better than that based on geometry and stiffness estimates alone. The addition of sacrificial layers to future 2D and 3D cell culture platforms will enable improved cell placement and the complex suspension of cells across 3D constructs.

Vitreoretinal surgery requires very fine motor control to perform precise manipulation of the delicate tissue in the interior of the eye. Besides physiological hand tremor, fatigue, poor kinesthetic feedback, and patient movement, the absence of force sensing is one of the main technical challenges. Previous two degrees of freedom (DOF) force sensing instruments have demonstrated robust force measuring performance. The main design challenge is to incorporate high sensitivity axial force sensing. This paper reports the development of a sub-millimetric 3-DOF force sensing pick instrument based on fiber Bragg grating (FBG) sensors. The configuration of the four FBG sensors is arranged to maximize the decoupling between axial and transverse force sensing. A super-elastic nitinol flexure is designed to achieve high axial force sensitivity. An automated calibration system was developed for repeatability testing, calibration, and validation. Experimental results demonstrate a FBG sensor repeatability of 1.3 pm. The linear model for calculating the transverse forces provides an accurate global estimate. While the linear model for axial force is only locally accurate within a conical region with a 30° vertex angle, a second-order polynomial model can provide a useful global estimate for axial force. Combining the linear model for transverse forces and nonlinear model for axial force...

As intervenções realizadas na indústria do petróleo, com o objetivo de reparar estruturas e membros mecânicos representam hoje um alto custo financeiro. Essas operações envolvem ainda um elevado risco, por se tratar de áreas com perigo de explosão. A soldagem a arco voltaico consiste em uma das técnicas mais empregadas no sentido de realizar tais reparos, principalmente submersos. Contudo, a mesma possui uma série de inconvenientes, dentre os quais podem se destacar: realização de práticas de “doca seca” ou de soldas hiperbáricas, presença de poros no cordão de solda (quando em condições submersas), fragilização pela adsorção de hidrogênio da atmosfera, formação de fases frágeis com baixa tenacidade á fratura e altas energias de soldagem envolvidas. Nesse sentido, o reparo de trincas por atrito apresenta uma série de vantagens, por consistir de um processo realizado dentro da fase sólida. Menores temperaturas estão envolvidas e o processo não é influenciado pelo ambiente externo, minimizando os problemas no reparo de estruturas submersas. Assim, este trabalho teve como objetivo a otimização dos parâmetros do processo de reparo por atrito, dando-se especial atenção aos efeitos da geometria, da força axial e da rotação sobre a qualidade do reparo. O estudo foi realizado através de investigações metalográficas nos reparos obtidos...

A operação de rosqueamento interno é um processo de alta complexidade se comparado a outros processos convencionais, como furação, fresamento e torneamento. Além disso, existe pouca investigação a respeito da influência das condições de corte. Assim, um dos objetivos deste trabalho é buscar maiores conhecimentos sobre os fenômenos envolvidos no rosqueamento interno com macho de corte. Os materiais da peça utilizados neste trabalho também são relativamente novos e com grande aplicação na indústria automobilística, principalmente na fabricação de cabeçotes de motores de combustão interna. Neste trabalho foram utilizados machos de corte de aço-rápido com três canais retos (M6 X 1) revestidos com TiAlN (FUTURA). Foram analisadas a influência de diferentes condições de corte, onde foram variadas a velocidade de corte, forma de aplicação de fluido de corte e tipo de fluido. Os testes foram realizados em três materiais diferentes: ferro fundido vermicular da classe 350 e dois ferros fundidos ligados (CrCuSn e CrCuSnMo). Os resultados mostram a diminuição do torque e aumento da força axial com a velocidade de corte. O ferro fundido cinzento ligado ao CrCuSn foi o que apresentou a pior usinabilidade, considerando o torque...

O reparo por atrito (em inglês Friction Hydro Pillar Processing – FHPP) é um processo de soldagem no estado sólido surgido na década de 1990. Neste caso, um pino é colocado em rotação e pressionado contra um furo. Com este método é possível reparar defeitos nas estruturas através de uma sequência de pinos soldados ao longo do mesmo. Para isso deve haver uma sobreposição de reparos de modo a preencher todo o defeito. Esta técnica tem potencial para reparar estruturas de aço das indústrias offshore, uma vez que o processo reduz fortemente a fragilidade pelo hidrogênio e a porosidade. Neste trabalho foram investigados os efeitos da espessura da chapa na qualidade do reparo por atrito. Para isso foram realizados ensaios em chapas de aço com três espessuras (25,4, 38,1 e 50,8 mm), duas intensidades de forças axiais (60 kN e 120 kN) e duas velocidades de rotação (1400 rpm e 1700 rpm). Os materiais utilizados foram aço ASTM A36 para os blocos e aço ABNT 1010 para os pinos. As geometrias dos pinos e dos blocos tiveram como referência trabalhos desenvolvidos no próprio Laboratório de Tecnologia em Atrito e Desgaste (LTAD). Para determinar as dimensões dos blocos foi feita simulação em elementos finitos, definindo com isso que...

In this paper, a variety of analytical/integral methods are compared for calculating the axial force between a cylindrical magnet and a “thick” solenoid that consists of many turns both radially and axially. Two newly developed techniques are introduced: one being numerical integration-based and the other completely analytical. These are compared to two other techniques, each shown to have various advantages in different contexts. One method in particular is introduced that is shown to be the most computationally efficient in the majority of actuator designs. This method is then used to optimize a typical “sleeve-type” magnet-coil actuator based on the cost function of peak force, and it is shown that optimal values of wire thickness and magnet-coil geometry can be chosen based on desired coil impedance and magnet volume.; Will Robertson, Ben Cazzolato, and Anthony Zander

Twelve identical cantilever-type column specimens were subjected to load paths of cyclic unaxial or biaxial flexure with axial load, to provide data for the development and calibration of mathematical models of columns subjected to biaxial bending. The specimens had a shear span ratio of 6.0 and were overdesigned in shear, so that their behaviour and damage were controlled by flexure. The only test variable was the load path. In 10 of the axial load was essentially kept constant and in the rest it varied, either simultaneously or indipendently of the transverse loads and/or displacements. Very strong coupling was observed between the two directions of bending and between these two directions and the axial direction. The coupling between the two transverse directions significantly increased the hysteric energy dissipation. This increase was related to the phase lag of the vector of biaxial deflections relative to that of biaxial transverse loads, and the two relative rotation of the biaxial load path with respect to that of biaxial deflections. Cycling of the deflections had two effects on axial deformations: 1) gradual permanent shortening for low-to-medium axial loads, or a gradual extension, which turned into shortening when failure was approaching...

Steel beam-to-column joints are often subjected to a combination of bending moment and axial force. Current specifications for steel joints do not take into account the presence of axial forces (tension and/or compression) in the joints. A single empirical limitation of 5% of the beam's plastic axial capacity is the only enforced provision in Eurocode 3--Part 1.8. The objective of the present paper is to describe an experimental program carried out at the University of Coimbra on extended endplate beam-to-column joints to try to extend the component method philosophy to the combined action of bending moment and axial force. To fulfil this objective, a set of seven extended beam-to-column joints were tested. This paper provides a detailed description of this experimental programme focusing on the moment-rotation curves and individual component assessment. Finally, it reveals that the presence of an axial force on the beam significantly modifies the joint response.; http://www.sciencedirect.com/science/article/B6V2Y-4CPD72K-1/1/06c77cd246ec1e3daa26d5d1c4b8cfbc
