Off-Center, Low Velocity, Transverse Normal Impact of a Simply Supported Plate.

Abstract

A theoretical solution for the response of a simply supported plate to off- center low speed transverse impact is presented. This solution is empirically corrected, on the basis of viscoelastic beam analysis, to admit damping. Comparison of the numerical predictions of the corrected theory with central impact test results on graphite-epoxy composite laminates shows good agreement. The structural dynamic response model consists of a special orthotropic plate impacted by a rigid mass. Initial displacement and velocity distributions were assumed and the solution method utilized the finite Fourier sine transform and Laplace transforms with respect to both space and time. (Author)
