A combined boundary element/finite element method (BEM/FEM) in the time domain is developed and applied for solving two-dimensional dynamic elastoplastic problems. The BEM is used for the portion of the structural domain expected to remain elastic, while the FEM for one expected to become elastoplastic during the deformation history. The two methods are coupled together at their interface through equilibrium and compatibility. The solution procedure is based on a step-by-step time integration algorithm of the Newmark type associated with an iterative scheme.
