Abstract : A finite element solution for the response of a clamped plate subjected to central low speed transverse impact is presented. The solution is empirically corrected, on the basis of viscoelastic beam analysis, to admit damping. Comparisons of the numerical predictions of the corrected theory with central impact test results on graphite-epoxy composite laminates show excellent agreement for two of the three test studies.
