WebBased on the broad detection of DEM and background cells, the local MP cells intersection with DEM blocks or surface, are defined as the interaction background domain which is used to perform the next coupling calculation. The contact forces are computed by using DEM scheme according to the contact geometry and particles’ material properties. WebHowever, surface-based cohesive behavior is typically easier to define and allows simulation of a wider range of cohesive interactions, such as two “sticky” surfaces coming into contact during an analysis. Surface-based cohesive behavior is primarily intended for situations in which the interface thickness is negligibly small.

WebCohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface). Adhesive forces between the molecules of a liquid and different molecules composing a surface in contact with the liquid are responsible for phenomena such as surface wetting and capillary rise. WebYou can define cohesive behavior properties that are accounted for in surface contact interactions. For more information, see Contact cohesive behavior. In addition, you …

WebIn their proposed approach, the cohesive force and work of adhesive peeling are scaled cubically in the coarse-grained system. Sakai et al.
