## Abstract

The first order plate theories with correction factors are generally assumed to predict accurately the plate modes which have half wave lengths greater than the plate thickness, and at frequencies up to 20% higher than the fundamental thickness shear frequency. In this study, this assumption is assessed by comparing the straight crested wave solutions of the plate theories with those of the three-dimensional elastic equations of motion. In particular, the frequency spectra for bandwidths of resonant frequencies vs. the aspect ratio of length to thickness are compared for three sets of plate equations including the first order Mindlin plate equations, the third order Mindlin plate equations, and the third order Lee and Nikodem plate equations.
