'''Discrete element methods''' (DEM) comprise a family of related mathematical tools for determining the [[kinematic]] behavior of finite-sized particles[[particle]]s.

As defined by Cundall, ''discrete element methods'' allow:

#finite [[displacement]], [[rotation]] and separation of elements, and<br>

#new particle contacts are recognized algorithmically[[algorithm]]ically as the [[computer simulation|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]].
