摘要
采用8结点等参元并在裂纹尖端采用三角形奇异元对三点弯曲试样在单调加载过程中的裂纹扩展进行了有限元模拟计算。并与实验结果进行了对比。
In this paper, the finite element method is used to simulate the stable crack growth in three point bendtest pieces which are under the monotonic loading pattern. Both eight-node isoparametric elements and degenerate trian-gular elements have been incorporated in the programme. The results are compared with the experimental data.
