A piece-wise-linear elasto-plastic constitutive model for mixed-mode interface cracks
-
摘要: 基于分段线性塑性理论和断裂力学理论 ,提出了一种二维的全量形式和增量形式的粘性裂纹的本构模型。给出了相应的数值试验结果。Abstract: On the basis of piece-wise-linear plasticity and fracture mechanics, this article presented a 2-dimensional holonomic and nonholonomic constitutive model for cohesive crack of concrete-like materials. Corresponding numerical tests are carried out at the local level.
