摘要：

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

Meshless methods is introduced briefly in the paper. The shape function of reproducing kernel particle method, which is a common meshless method, is proposed. A design sensitivity formulation for elastoplasticity in finite deformation and a die design sensitivity formulation for a frictional contract problem are discussed.
