Research on Nodes Factors Affecting Computational Precision of Element-free Galerkin Method

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,simultaneously,develop element-free computational program based on Matlab.Furthermore,study the layout method and the impact on computational 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.
