'''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<br>

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 [[Peter A. Cundall | Cundall]] in [[1971]], and the [[discontinuous deformation analysis]] (DDA) proposed by [[Gen-hua Shi | Shi]] in [[1988]].
