摘要
针对采用有限元法在模拟裂纹扩展所遇到的问题,探讨了模型的建立、网格的划分、断裂准则的应用以及网格重组技术的运用.
The crack growth modeled by the FEM in two dimensions has encountered several problems, such as the establishment of models, the classification of grids meshed, the application of the fracture criterion and the grid\|rebuilt technique. All these are discussed in our paper.
