A semi-spring and semi-edge combined contact model in CDEM and its application to analysis of Jiweishan landslide
Continuum-based discrete element method (CDEM) is an explicit numerical method used for simulation of progressive failure of geological body. To improve the efficiency of contact detection and simplify the calculation steps for contact forces, semi-spring and semi-edge are introduced in calculation....
