tensile failure criterion

基本解釋

The tensile strength failure criterion is used, and stress-displacement model is adopted to alleviate the sensitivity on mesh size in the softening region.
混凝土細觀結(jié)搆的破壞由最大拉應力準則判別，對於軟化段，採用了應力-張開位移模型以緩解計算結(jié)果的網(wǎng)格依賴性。
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：極限疲勞割線模量衰減率可作爲混凝土發(fā)生拉-壓疲勞破壞的標志；
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.
計算中用應力波傳播的加卸載判別準則來決定單元的加卸載狀態(tài)，對受拉破壞單元進行內(nèi)部應力調(diào)整和應力轉(zhuǎn)移。
