Experimental and Numerical Investigation of the Dynamic Behavior of Clamped Thin Panel Subjected to Underwater Impulsive Loading

Abstract The dynamic response and failure mechanism of clamped thin aluminum alloy plates subjected to underwater impulsive loading are investigated by laboratory experiments and finite element (FE) simulations. The effects of plate thickness, impulsive loading and fluid-structure interaction on failure modes in clamped thin aluminum plates are comprehensively assessed in this study. The underwater explosive shock loading experiments were performed by underwater non-contact explosive simulator to identify failure modes of target plates under loads with different intensities. The 3D digital ima...
