摘要

The report presents a new analysis procedure, which is a combination of the finite element method (FEM), the boundary element method (BEM) with particular integrals, modal analysis and substructuring. The difficulty of the nonsymmetric matrix generally introduced from the BEM method with nonsymmetric and full matrix at the interface between the FEM and the BEM methods is overcome by using the described procedure. A new boundary integral equation, which adopts a frequency-independent fundamental solution, is derived for solving the scalar wave equation.
