摘要：
Mixed-mode dynamic crack propagation in concrete is studied using the element-free Galerkin (EFG) method. The EFG methodology allows for arbitrary crack growth in terms of direction and speed. A fracture process zone (FPZ) model is used for fracture in concrete. Comparisons are made to mode Land mixed-mode experiments on concrete three-point-bend specimens. Good agreement is achieved with the experimental results.
