Stress-strain measurementsnumerical simulationtensile testingneckingFull-range strain hardening behaviour, containing the post-necking stage, is difficult to account for in detail. Hence, a Swift-Voce (S-V) model was used to describe the full-range stress-strain behaviour of 7050-T7451 aluminium ...

Based on these models and experimental data a stress–strain–temperature model is proposed which incorporates the effect of transient strain implicitly. This model can be easily incorporated into existing commercial finite element analysis software. A numerical example on a wall element heated on two ...

comparing the exist models, presents the three-stage stress-strain model proposed by Quach, which is defined using the three basic Ramberg-Osgood parameters and could be used in structural design by the current codes, considering the Quach equation as the most accurate constitutive equation for stai...

The stress–strain relationship for strain hardening and softening of high-purity aluminum and copper, which were deformed by equal channel angular pressing (ECAP) at ambient temperature, was analyzed by combining the Estrin and Mecking (EM) model and an Avrami-type equation with experimental data...
The influence of strain has been incorporated by employing an Arrhenius-type constitutive equation, considering the related material constants as functions of strain. The comparison of results indicated good agreement between the predicted and measured flow-stress values in the relevant temperature range....
It is found that pattern transition of stress-strain relation exists in medium density calcareous sand under different confining pressure. 以南沙群岛永暑礁的钙质砂为研究对象,通过三轴排水剪切试验发现:中密钙质砂在不同围压下的应力应变关系具有转型现象,提出了能反映硬、软化和剪胀、缩转型的非线性弹性应力...
