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...

A constitutive equation (sometimes also called a material model or constitutive model) is a relationship that describes how a material behaves, for example, the stress response for a given strain, or the heat transfer for a given temperature gradient. The constitutive equations are what distinguish...

Stress, Strain, and Constitutive Relations Abstract Consider the two structural members in Figure 2.1, each acted upon by an applied weightWthat is much larger than the individual weightsmg, which we therefore neglect. From statics, we know that if these two members are in equilibrium, then Σ...
For example, Sherwood31modified the basic thermodynamic parameters of Biot consolidation and the chemical potential related to the pore fluid; Hueckel32and Gajo et al.33considered that clay was contaminated in the stress history and studied the electro-chemical–mechanical constitutive equation under the...
To investigate the mechanical properties and constitutive equation of pressed CL−20 based aluminized explosives, the stress-strain curves at different strain rates are obtained by quasi-static and dynamic compression tests using universal testing machine and Split Hopkinson Pressure Bars (SHPB), respect...
6) stress-strain model 应力-应变模型 1. In order to properly understand the mathematical model of stress-strain relationships of frozen soil,strength index is defined and employed to establish mathematical property sets of two traditional stress-strain models,namely hyperbolic model and exponential ...
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...
