Material Point Method

The material point method (MPM) is a hybrid particle-cell method that represents continua by a number of Lagrangian elements, termed the material points. It adopts a finite element like approach on a fixed background mesh to calculate gradient terms such as the deformation gradient and to exchange information between particles. The MPM is quite attractive for solving engineering problems with large deformations.

Our group is mainly interested in the mathematical aspects of the MPM and has been working on the integration of concepts from Isogeometric Analysis.
