摘要：

A numerical method which admits discontinuous variable coefficients in the wave equation is employed for handling the wave propagation in composite materials. The resulting algebraic eigenvalue system is simplified by a rank-one matrix modification that reduces the computing time by at least one order of magnitude. The first five modes are accurately and efficiently computed as a demonstration of the method presented. © 1974 by ASME.
