A NOTE ON CLAMPED CIRCULAR PLATES UNDER IMPULSIVE LOADING

A previously proposed approximate theory is employed in this article t o examine the dynamic inelastic deformation and failure of clamped cir cular plates subjected to uniformly distributed impulsive loads. Based on the principle of energy conservation and the assumption of equival ent work done, the problem of an impulsively loaded clamped circular p late is treated as that of an identical plate subjected to an equivale nt impact loading. It is shown that good agreement is obtained between the solutions using this method and the experimental data for clamped circular plates in terms of the maximum permanent transverse deflecti ons, failure modes, and critical input impulses that cause plate failu re due either to tensile tearing or to transverse shear.
