Abstract
The dynamic characteristics of the ship's plate frame is an important factor in determining the structural quality of the ship. In this paper, the structural impact response spectrum and the deformation displacement of the plate structure under the blast load are used as indicators to assess the impact resistance. A finite element model of the plate structure and flow field is established. The dynamic characteristics of composite laminated plates with different characteristics under the underwater explosion loads are analyzed. The results show that the elastic modulus and Poisson’s ratio of the composite laminated, the number of layers, the fiber laying angle, all affect the mechanical properties and impact resistance of the plate structure.
