TI - Weak Coupling of the Symmetric Galerkin BEM with FEM for Potential and Elastostatic Problems T2 - Computer Modeling in Engineering \& Sciences PY - 2006 VL - 13 IS - 1 SN - 1526-1506 AB - With reference to potential and elastostatic problems, a BEM-FEM coupling procedure, based on the symmetric Galerkin version of the BEM, is developed; the continuity conditions at the interface of the BE and FE subdomains are enforced in weak form; the global linear system is characterized by a symmetric coefficient matrix. The procedure is numerically tested with reference first to 2D potential problems and successively to 3D elastoplastic problems (with plastic strains confined to the FE subdomain).
