A previously proposed approximate theory is employed in this article to examine the dynamic inelastic deformation and failure of clamped circular plates subjected to uniformly distributed impulsive loads. Based on the principle of energy conservation and the assumption of equivalent work done, the problem of an impulsively loaded clamped circular plate is treated as that of an identical plate subjected to an equivalent 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 deflections, failure modes, and critical input impulses that cause plate failure due either to tensile tearing or to transverse shear.
