Abstract : The dynamic step pressure loads required to produce snapping are determined experimentally for two shallow spherical shell models. The resulting critical step pressures are compared with static buckling pressures that were obtained from the results of a nondestructive buckling test. The comparison reveals that the critical step pressures were between 55 and 58% of the static buckling pressure for one model and between 63 and 64% of the static buckling pressure for the other model. The measured supercritical response of the shells was similar to the predictions of theory. (Author)
