A COMPARISON OF THEORY AND EXPERIMENTS ON THE DYNAMIC PLASTIC BEHAVIOR OF SHELLS

A comparison is made between the predictions of an approximate theoretical rigid-plastic procedure and some experimental values of the permanent deflections of hemispherical shells and cylindrical shell panels loaded impulsively. The initial kinetic energy of the dynamic loads in these tests was considerably larger than the maximum amount of strain energy which the shells could absorb in a wholly elastic manner. It emerged that reasonable agreement was obtained for the strain rate insensitive shells examined here and elsewhere which should provide encouragement for the further development of these approximate procedures.
