     predicting the dynamic response of submerged vehicles subjected to hydrostatic pressure and underwater shock loading is of great interest to many structural designers and engineers for improving material and configuration design in recent years. in this paper, the finite element method is used to evaluate the dynamic response of a submerged cylindrical foam core sandwich panel subjected to shock loading. the sandwich panel consists of a foam core surrounded by fiber-reinforced laminates. the effect of fluid–structure coupling is included in the finite element analysis whereas the fluid is assumed to be compressible and inviscid. time histories of circumferential stress for different composite plies are presented in graphical form and the effects of core type on circumferential stress and velocity of stand-off point are also investigated. additionally, the distribution of pressure in fluid domain and the deformation of cylindrical foam core sandwich panel are estimated. to the best of the authors’ knowledge, the specialized literature addressing the dynamic response of submerged cylindrical foam core sandwich panel to underwater shock loading is rather scanty. this work is likely to fill a gap in the specialized literature on this topic.
