An efficient and locking?free material point method for three?dimensional analysis with simplex elements

The Material Point Method is a relative newcomer to the world of solid mechanics modelling. Its key advantage ability model problems having large deformations while being relatively close standard finite element methods, however its use for realistic engineering applications will happen only if material point can be shown both efficient and accurate (compared methods), when modelling complex geometries with range models. In this paper we present developments method aimed at realizing these goals. contribution provided here development that avoids volumetric locking (arising from elastic or elasto-plastic behavior) using low-order tetrahedral elements background computational mesh, hence allowing unstructured grids used geometries. We also show effectively parallelized improve efficiency.
