✦ Synopsis

Based on energy functional and with the inclusion of high-order incompatible dynamic displacement modes, a formulation for 3-D "nite dynamic element method (DEM) is developed and a new 8-node solid element is derived in this paper. Numerical results exhibit that the present method provides the most economical and e$cient solution when compared with the usual FEM and DEM.
