基于Griffith准则的准静态裂纹扩展的变分离散元法
Quasi-static crack propagation with a Griffith criterion using a variational discrete element method
摘要：
采用变分离散元法模拟了准静态裂纹扩展。裂纹被认为是通过网格刻面在网格单元之间传播。弹性行为由连续的力学参数（杨氏模量和泊松比）参数化。一个离散的能量开裂准则耦合到一个离散的扭结准则指导开裂过程。二维数值例子来说明该方法的鲁棒性和通用性。
英文摘要：
A variational discrete element method is applied to simulate quasi-static crack propagation. Cracks are considered to propagate between the mesh cells through the mesh facets. The elastic behaviour is parametrized by the continuous mechanical parameters (Young modulus and Poisson ratio). A discrete energetic cracking criterion coupled to a discrete kinking criterion guide the cracking process. Two-dimensional numerical examples are presented to illustrate the robustness and versatility of the method.
