Abstract

A Boundary Element Method /Finite Element Method (BEM/FEM) hybrid scheme in the time domain is developed for the dynamic response determination of elastoplastic systems under plane strain or plane stress conditions. The FEM is used for that part of the system expected to become elastoplastic, while the BEM for its remaining part expected to stay elastic. The BEM and FEM domains of the system are connected at their interface through equilibrium and compatibility. The solution procedure follows the step-by-step integration algorithm of Newmark and employs iterations at every time step. Numerical examples involving stress analysis of steel plates and soil-structure interaction are presented to illustrate the proposed scheme and access its advantages.
