What is Coupled FEM-DEM for Pile Penetration Analysis about?

This research proposal aims to model dynamic pile penetration in crushable sand using a coupled finite element-discrete element (FEM-DEM) approach. Prior research has shown that particle breakage influences soil behavior but is often not considered in numerical modeling. The proposal will develop a hierarchical multiscale FEM-DEM model where each finite element Gaussian point is attached to a DEM assembly of crushable particles. This will allow modeling of particle-scale interactions during dynamic pile ins
