Summary

Various lamination schemes are considered for square and rectangular plates excited by an instantaneously applied sinusoidal pressure distribution. Duhamel’s equation is utilized to obtain both temporal displacement and stress response on a modal basis. Modelling is based on an assemblage of quadrilateral finite elements that account for the effects of transverse deformation and rotatory inertia. The finite element formulation relaxes the Kirchhoff-Love assumptions and thereby provides good results for thin to moderately-thick plate geometries. Results compare quite well with those found in the literature and thus demonstrate the utility of the formulation in obtaining time-dependent results.
