Discrete element methods (DEM) comprise a family of related mathematical tools for determining the kinematic behavior of finite-sized particles. |
Discrete element methods (DEM) comprise a family of related mathematical tools for determining the kinematic behavior of finite-sized particles. As defined by Cundall, discrete element methods allow 1. finite displacement, rotation and separation of elements, and 2. new particle contacts are recognized algorithmically as the simulation proceeds. |
Two prominent members of the DEM family are the [distinct element method]? proposed by Cundall? in 1971, and the [discontinuous deformation analysis]? (DDA) proposed by Shi? in 1988.
