Abstract

In this paper, a pre-processing toolkit for three-dimensional extended finite element method (X-FEM) is discussed and employed for three-dimensional arbitrary crack growth simulation. The major topics includes the framework of X-FEM toolkit, formulations of 3D crack using level sets, the data structure of pre-processing toolkit and corresponding implementation. Using simple 11times11times11 cubic mesh and tee-joint as benchmark, the results of pre-processing are presented and verified.

三维X-FEM预处理工具箱
本文讨论了三维扩展有限元法(X-FEM)的预处理工具箱,并将其用于三维任意裂纹扩展模拟。主要内容包括X-FEM工具箱的框架、基于水平集的三维裂纹计算公式、预处理工具箱的数据结构及其实现。以简单的11times11立方网格和三节为基准,给出了预处理结果并进行了验证。
