The MaterialPoint Method, is an extension from the Particle-in-cell Method incomputational fluid dynamics to computational solid dynamics, and is aFinite element method-based particle method. It is primarily used formultiphase simulations, because of the ease of detecting contact withoutinter-penetration. It can also be used as an alternative to dynamic FEMmethods to simulate large material deformations, because there is nore-meshing required by the MPM. In the MPM, Lagrangian point masses, ormaterial points, are moved through a Eulerian background mesh. At theend of each calculation cycle, a 'convective' step occurs, in which themesh is reset to its original position, while material points remain intheir current positions. There are two key differences between the PICand MPM. The first one is that the MPM is formulated in the weak formsimilar to that for the FEM so that the FEM and MPM could be combinedtogether for large-scale simulations.…
