WebApr 5, 2024 · The contact forces due to collisions are approximated using a soft contact model developed by Cundall and Strack (1979). In this model, the colliding colloids are permitted a limited overlap, and the colliding force is calculated depending on the area of the overlap cross-section, mechanical properties of materials, and velocities of the pair ... WebAug 2, 2024 · However, internal instability is a particle-scale problem, whereas most of the criteria currently used to assess instability are derived from macro-scale laboratory testing. Therefore, the particulate discrete element method (DEM) (e.g., Cundall and Strack ) could be used to model and evaluate these particle-scale problems (O’Sullivan ).
WebThe method is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the particles modelled …
