Abstract

Particle methods have been increasingly used in numerical simulations of complex problems in both sciences and engineering. A plethora of different particle methods exists of which the material point method (MPM) is a promising method that is able to deal with high strain rate problems that involve contact, impact, damage and fragmentation. Particle domains in the MPM are currently represented by quadrilaterals in two dimensions. Extension to polygonal particle domains is presented based on a simple sub-division of the polygons into sub-triangles. This allows MPM simulations to be carried out for structures and materials discretized by Voronoi tessellations. Performances of the proposed method are illustrated by means of numerical simulations.
