WebOne such method is the Discrete Element Method (DEM) which originates from Cundall and Strack and has found many new applications in different fields spanning chemical engineering, pharmaceuticals, powder metallurgy, agriculture and many others.
WebIntroduced by Peter Cundall (1971), the DEM was developed for the analysis of rock mechanic problems using deformable polygonal-shaped blocks and then applied to soils (Cundall and Strack, 1979). This led to the development of Itasca's UDEC (Universal Distinct Element Code) and 3DEC (Three-Dimensional Distinct Element Code) software.
