Abstract

It has been more than a decade since MESH-FREE METHODS gained considerable attention in engineering and science. The main distinction of the methods with respect to the FEM is their shape functions. In this regard, DIFFUSE ELEMENT METHOD (DEM) employs Least-Squares (LS) approximation, while ELEMENT-FREE GALERKIN METHOD (EFGM) benefits from Moving-Least-Squares (MLS) approximation for shape function construction. In order to compare the results of the methods, Boussinesq problem, which has closed-form solution, is used as a benchmark. The results are compared in displacement and stress fields. Finally, it is concluded that EFGM error is less than DEM in the both fields. This is more pronounced in stress field due to weight function being constant in DEM.
