Abstract
- Based on a FE–BE coupling algorithm, an automatic implementation procedure for the coupling of the ABAQUS with a self-written linear elastic BE code is introduced for dynamic elastoplastic problems. User subroutine (UEL) is developed to enable the incorporation of the BE capabilities within the ABAQUS. Each closed BE domain in the mixed FEM/BEM model is defined as a finite super-element for which the effective stiffness and effective forces are generated by the BE code and hence can be assembled to the global FE formulation. The user can not only benefit from the powerful pre- and post-disposal functions of the ABAQUS, but also deal with systems with infinite extension by using the BEM as a supplement. Basic steps of the automatic coupling procedure are explained and necessary background information is provided. The analysis is conducted through several examples regarding 2D time domain responses. The results of the analysis document a very good agreement between the present solutions and analytical and other numerical results, confirming thus a successful implementation of the developed automatic coupling procedure.
