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(xì)觀結(jié)構(gòu)的破壞由最大拉應(yīng)力準(zhǔn)則判別，對(duì)于軟化段，采用了應(yīng)力-張開(kāi)位移模型以緩解計(jì)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為混凝土發(fā)生拉-壓疲勞破壞的標(biāo)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(jì)算中用應(yīng)力波傳播的加卸載判別準(zhǔn)則來(lái)決定單元的加卸載狀態(tài)，對(duì)受拉破壞單元進(jìn)行內(nèi)部應(yīng)力調(diào)整和應(yīng)力轉(zhuǎn)移。
