rupture strain

It is concluded that the final collapse of the structure is decided by the rupture strain that is deduced from the critical damage variable.

准则表明最终的结构破裂取决于与临界损伤变量密切相关的断裂应变。

The measurements indicate that the weak-link of the PET fibres is the defeats on surface layer and their propagation and that the mechanical properties of fibre weak-links are low stress, low strain and low work of rupture according to the analysis of the typical tensile curve.

结果表明，涤纶纤维的弱节主要是表层缺陷及其扩展所引起的，其力学性能为低应力、低应变、低断裂功特征。

Strength modeling for threshold effect of strain rate and local second rupture of rocks

岩石强度应变率阈值效应与局部二次破坏模拟探讨

The methods of creep test to get both curves of tensile creep rupture load vs time and creep strain vs time are compared. The procedures to extrapolate the two types of creep curves are presented.

比较了获得拉伸蠕变破坏荷载-时间曲线以及蠕变应变-时间曲线的试验方法，给出了外推这两种蠕变曲线数据的处理步骤。
