WebThe discrete element method (DEM) is a numerical model that characterizes the mechanical behavior of solid particles, which was initially proposed by Cundall and Strack (1979). In this model, Newton’s second law describes the motion of the particles and the force–displacement law is applied to determine the contact forces from displacements. WebJan 4, 2024 · Cundall, O.

A. … WebIn blocky DEM (Cundall and Strack, 1979), every block is assumed to be a rigid body and the dynamic behavior of each block is governed by Newton’s second law of motion. In the algorithm, the most important issues are the contact detection and contact force calculation which influence the efficiency and accuracy. WebOne should also quote the widely used distinet element method, originating from the works of Cundall and coauthors (Cundall and Strack 1979; Cundall 1988), which makes use of an explicit ?nite-difference numerical scheme for computing the displacements of the blocks considered as rigid or deformable bodies.
