effective stress tensor的意思|示意

Using the theory of damage mechanics and fracture mechanics, the damage tensor, effective stress tensor and damage strain, etc. of rock mass are defined, propagation equation of damage is developed.

运用损伤力学以及断裂力学理论，定义了岩体损伤张量、有效应力张量、损伤应变等，建立了损伤演化方程，从而建立了多裂隙岩体的损伤断裂模型。

Damage tensor and pure stress are studied on such a body. Assuming an average effective stress, the constiutive relation for the equivalent damaged body and the reiteration formula- about the fi…

在提出平均有效应力的概念之后，完成了有限单元法的离散化过程，最后给出了一个完整的计算不连续块体的数值方法。
