An exact analytical solution is used for comparison with three wave-codes. The computer wavecodes employed in the comparison were HONDO, TOODY, and THREEDY. HONDO is a two-dimensional code based on the Galerkin finite element method in a time differenced form; TOODY is a two-dimensional code based on the von Neumann-Richtmyer, artificial viscosity, finite difference method; and THREEDY is a three-dimensional code based on the operator splitting method. Referring the error to a dimensionless L/sub 1/ norm, at a point in the plate, and for two transit times the errors found were as follows: Implicit THREEDY, .1315; TOODY, .0800; HONDO, .0671; explicit THREEDY, .0569.
