【 摘 要 】

This study presents a hybrid BEM-FEM procedure for the dynamic analysis of elastoplastic models. In this hybrid approach, boundary node and internal point displacements are evaluated considering the time-domain BEM formulation (initial stress approach), and stresses are computed taking into account FEM techniques (domain discretization is only necessary where non-linear behaviour is expected to occur). This hybrid methodology is very appropriate to model infinite or semi-infinite elastoplastic models and, at the end of the paper, three numerical applications are presented, illustrating the potentialities of the proposed formulation.
