Description	Journal: Iop Conference Series: Earth and Environmental Science Studying the structural dynamic response characteristics under the action of underwater explosion load had great significance for improving the anti-explosion and anti-impact performance of ships. The autodyne numerical simulation software was used to calculate the dynamic response of target under the underwater explosion. A series of movable observation points are set on the target and the y-axis coordinate-time image of each observation point is extracted after the target plate is completely broken at the boundary. We find that there is a tensile wave propagating in the y-axis direction inside the target plate before the target plate is in a severely bent state. The intensity variation of the tensile wave along the thickness direction of the target plate is studied. The tensile wave has less influence on the back-explosion surface and have an obvious effect on the destruction of the detonation surface. The effect of the tensile wave on the boundary was studied. The tensile wave contributes to the fracture of the target at a fixed boundary.
