摘要
随着计算机技术的发展,有限元仿真技术被大量应用于疲劳计算中。然而,在进行疲劳分析时,常规有限元法往往对于网格的划分限制较大,工作量大,效率低。文章采用扩展有限元法对疲劳裂纹扩展进行仿真分析,简化了网格划分过程,并通过与试验结果的对比,证明了该方法的准确性。
With the development of computer technology, finite element simulation technology is widely used in fatigue calculation. However, in the fatigue analysis, the conventional finite element method often has great restrictions on the division of grid, heavy workload and low efficiency. In this paper, the fatigue crack growth is simulated and analyzed using the Extended Finite Element Method (XFEM), the process of meshing is simplified, and the accuracy of the method is proved by comparing with the experimental results.
