Tensile Failure Criterion

In calculation, adopted load-unload criterion of stress wave propagation was to decide load-unload state of element and to adjusts and transfers internal stress for tensile failure element as well.

计算中用应力波传播的加卸载判别准则来决定单元的加卸载状态，对受拉破坏单元进行内部应力调整和应力转移。

They are mainly concerned with the tensile and compressive behavior, energy absorption, dynamic impact, failure criterion and constitutive relation, creep, fatigue and fracture of these materials.

这些工作主要讨论了金属泡沫材料的拉伸、压缩、能量吸收、动态冲击、失效准则、本构关系、蠕变、疲劳和断裂等力学性能。
