摘要：
A dual boundary element method program was developed to study the fictitious frequencies numerically. The positions of fictitious frequencies for the exterior problems using the singular integral equations and hypersingular integral equations formulation are plotted. Numerical results using the dual BEM program are verified in comparison with the analytical solutions. It is shown that the integral formulation, either singular or hypersingular equation, has different fictitious frequencies.
