The study proposes an MPM-FEM hybrid analysis method for simulating granular mass-water interaction problems, which is tested for accuracy and demonstrated through numerical examples to show its capability in simulating fluid motions induced by granular mass movements.
The present study proposes an MPM (material point method)-FEM (finite element method) hybrid analysis method for simulating granular mass-water interaction problems, in which the granular mass causes dynamic motion of the surrounding water. While the MPM is applied to the solid (soil) phase whose motion is suitably represented by Lagrangian description, the FEM is applied to the fluid (water) phase that is adapted for Eulerian description. Also, the phase-field approach is employed to capture the free surface. After the accuracy of the proposed method is tested by comparing the results to some analytical solutions of the consolidation theory, several numerical examples are presented to demonstrate its capability in simulating fluid motions induced by granular mass movements.
