Deformation behavior of a stiffened panel subjected to underwater shock loading using the non-linear finite element method

Given the superior strength-to-weight ratio, stiffened panels have been used extensively in the main structure of ships and underwater vehicles. The loads acting on a stiffened panel in a ship is in-plane compression or tension, resulting from the overall hull-girder bending moment or torsion, shear force resulting from the hull-girder shear force, and lateral pressure resulting from the external wave or shock loading.In modern sea combat, in which strike power has increased markedly, the structures of naval ships must be designed to with-stand shock loads resulting from weapon hits.Studies examining the dynamic response of a structure to shock loads typically employ numerical simulation or analytical and experimental methods.The sudden release of energy from underwater explosions of a conventional high-explosive or nuclear weapon generates a shock-wave and forms a super heated, highly compressed gas bubble in the surrounding water.In this tutorial Deformation behavior of a stiffened panel subjected to underwater shock loading using the non-linear finite element method has been studied in ABAQUS with UNDEX method. You can see schematic of the simulation at below figure

Dynamic analysis is appropriate for this type of phenomenon and you can see some figures of results at below figures
