Degenerate scale occurs once the boundary integral equation (BIE) is employed to solve plate problems. There are two ways to be considered. First, the degenerate kernel for expressing the closed-form fundamental solution is utilized to study the occurring mechanism for circular and elliptical plates using polar and elliptical coordinates, respectively. Second, the BIE is discretized and reformulated to a 4 by 4 eigenproblem to obtain degenerate scales instead of the direct-searching scheme. Analytical degenerate scales for the circular and elliptical shapes are obtained while numerical results for general shapes are also considered.
