Abstract
Based on energy functional and with the inclusion of high-order incompatibl e dynamic displacement modes, a formulation for 3-D finite 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 efficient solution when compared with the usual FEM and DEM . Copyright (C) 2000 John Wiley & Sons, Ltd.
