Coupled finite element-discrete element method (FEM/DEM) for modelling hypervelocity impacts
TLDR
In this paper , a coupled finite element-discrete element method (FEM/DEM) was used to predict the shape of the debris cloud as a function of shield thickness, and a parametric study was performed to investigate the sensitivity of key model parameters.About:
