DEM-simulation of thin elastic membranes interacting with a granulate

Abstract For a wide range of applications, we need DEM simulations granular matter in contact with elastic flexible boundaries. We present novel method to describe the interaction between particles and membrane. Here, standard mass-spring model approach is supplemented by surface patches given triangulation In contrast models, our simulation allows for an efficient even large particle size dispersion. The coarsening system leading substantial increase computation efficiency. demonstrated benchmarked triaxial test.
