A dynamic implicit 3D material point-to-rigid body contact approach for large deformation analysis
Robert E. Bird, Giuliano Pretti, William M. Coombs +6
Accurate and robust modelling of large deformation three dimensional contact interaction is an important area of engineering, but it is also challenging from a computational mechan…

A stable poro-mechanical formulation for Material Point Methods leveraging overlapping meshes and multi-field ghost penalisation
Giuliano Pretti, Robert E. Bird, Nathan D. Gavin +2
The Material Point Method (MPM) is widely used to analyse coupled (solid-water) problems under large deformations/displacements. However, if not addressed carefully, MPM u-p formul…
