The main factors such as pressure, the third invariantofstress tensor, strain hardening and softening, stain rate and tensile damage have been taken into account in the constitutive model.
该本构模型全面考虑了压力、应力第三不变量、变形的硬化和软化、应变率强化以及拉伸损伤等各个影响因素。

The tests prove that saturated soils are a kind of strain hardened media and stress wave will maintain shock wave characteristic invariant during shock wave dynamic loading.
