Research on Nodes Factors Affecting Computational Precision of Element-free Galerkin Method
摘要
Abstract
Computational precision of MLS-based EFG is affected by many factors. In order to analyze the influence of element-free Galerkin method for nodes distribution,by analyzing the classical cantilever beam problem,define an energy norm as error index,simulta-neously,develop element-free computational program based on Matlab. Furthermore,study the layout method and the impact on computa-tional precision of element-free Galerkin method by node number. Also,investigate the computational precision and efficiency of EFG under uniform distribution method and the method of random distribution. Propose a mixed combination of the two distribution methods. The above analysis gives some useful conclusions.关键词
