　　The extended material point method(XMPM)has demonstrated its capabilities in the simulation of crack growth problems.Because of the use of the jump function as the enrichment function around the crack,the XMPM can describe the discontinues displacement and velocities by only one set of background grid mesh.

基于多重多级子结构的静力及瞬态有限元分析并行算法
本文基于多重多级子结构方法提出了用于大规模有限元静力及瞬态响应求解的并行分析框架，通过采用C++及MPI 并行编程技术，在SiPESC 上实现子结构并行计算。该并行算法根据多重多级子结构和并行计算环境对应关系，将有限元模型分解为多层子结构，由底层基本子结构并行凝聚计算开始，逐级求解直至顶层子结构，然后通过对子结构并行回代求解整体结构位移场，从而降低了整体模型子结构仿真的时间复杂度。同时为了优化子结
