摘　　要：采用无网格Galerkin方法来计算损伤问题与完全采用基于点的方法近似,不需要网格,避免了网格再生成的复杂过程,非常适合分析裂纹扩展、高速撞击和穿透等问题,具有广阔的应用前景。在众多无网格方法中,无网格Galerkin法以方法稳定、精度高、对离散点的不规则分布不敏感和最适合结构分析等优点受到了较多的关注。Adopt the element-flee Galerkin method to solve the problems of damage, with this method, mesh is not needed for the interpolation of the solution variables, and the mesh-free characteristic has distinct advantages to deal with high-speed impact, extremely large deformation, fracture and fragmentation problems, etc. Element- free method is promising in application. From many kinds of meshless methods, element-free Galerkin draw more attentions for its stability, high accuracy, insensitivity to distribution of discrete points.
