Abstract: | This paper presents a symmetric collocation BEM (SCBEM)/FEM coupling procedure applicable to 2-D time domain structural–acoustic
interaction problems. The use of symmetry for BEM not only saves memory storage but also enables the employment of efficient
symmetric equation solvers, especially for BEM/FEM coupling procedure. Compared with symmetric Galerkin BEM (SGBEM) where
double boundary integration should be carried out, SCBEM can reduce significantly the computing cost. Two numerical examples
are included to illustrate the effectiveness and accuracy of the proposed method.
