tensile failure criterion

基本解释

The tensile strength failure criterion is used, and stress-displacement model is adopted to alleviate the sensitivity on mesh size in the softening region.
混凝土细观结构的破坏由最大拉应力准则判别，对于软化段，采用了应力-张开位移模型以缓解计算结果的网格依赖性。
The results show that fatigue failure criterion of concrete under tensile-compressive stress can be indicated by ultimate attenuation rate of secant modulus.
研究表明：极限疲劳割线模量衰减率可作为混凝土发生拉-压疲劳破坏的标志；
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。
