Abstract

Abstract

In the present study, the dynamic response and shock-resisting properties of aluminum alloy lattice core sandwich panels under underwater shock loading were investigated using the non-explosive underwater shock loading device. The dynamic response of the sandwich plates was observed using a high-speed camera in collecting more information about the dynamic deformation history of the lattice sandwich plates. Based on the comparison of the experimental results of single-layered panels with the corresponding area mass, the effects of the lattice sandwich panel on the shock-resisting performance were studied. The results show that there is a quantitative relationship between the maximum deformation of the air-back plate of the lattice sandwich panels and the non-dimensional impulse of the underwater shock.
