In this paper, the stiffness degradation and damage failure in concrete dams subjected to strong ground motion are simulated by plastic-damage model based on damage index variable.
本文以拉压应力损伤因子为内变量，采用混凝土塑性损伤模型，分析了坝体在地震荷载作用下的刚度退化以及在多维应力状态下拉应力引起的损伤破坏。
Subtracting the elastic strain from the total strain yields the non-local plastic shear strain that depends on the flow stress and the damage variable.
将非局部总应变减去弹性应变，可得剪切带的非局部塑性应变。
