【 摘 要 】

The Finite Element Method (FEM) has become a standard tool in engineering, although its shortcoming in large deformation analysis is apparent. Mesh distortions are common in this area. In order to be able to investigate applications including large deformations or displacements of the material, advanced numerical methods are needed. In this study we introduce the Material Point Method (MPM) as a powerful tool to simulate applications including large deformations. This capability of MPM plays an important role in the study of land and rockslides, avalanches, mudflow, etc. Here we will present a brief introduction on the governing equations and the solution procedure of MPM. Based on the presented formulation and using a two dimensional program developed, a slope stability problem is solved to show the capability of this method to be used in studying geohazard related phenomena. At the end some concluding remarks and recommendations are presented.
