| Abstract: | This paper is devoted to the analysis of discontinuous BEM FEM coupling procedure. Discontinuous element is employed for the discretization of boundary integral equation to circumvent freedom constraints in coupling approach. Coupling scheme associated with discontinuous boundary elements is discussed in detail. Several techniques for solving coupled algebraic equations are implemented in the program developed by the authors. It is illustrated from the numerical results of 2 D elastostatics and transient response for fluid structure interaction, that the proposed procedure is feasible and efficient. |
