简要介绍了无网格方法 ,给出了一种常用的无网格方法———重构核粒子法形函数的表达形式 ;对基于无网格方法的有限变形弹塑性体的设计灵敏度分析和摩擦接触问题的模具设计灵敏度分析加以论述
A meshless method is briefly introduced. A commonly used meshless method, the expression of the normal function of the reconstructed core particle, is presented. The design sensitivity of the finite deformation elastic-plastic body based on the meshless method is also analyzed. Friction contact problem of mold design sensitivity analysis to be discussed
