The sandwich structure is widely used in ship repair and shipbuilding fields because of its superior corrosion resistance, high specific strength and high specific stiffness. In this paper, the marine I-type metal sandwich panel is taken as the research object, and the theoretical and numerical methods are used to study the impact resistance of the sandwich panel under the ice-impact load. An ice body material model suitable for the I-type metal sandwich plate and the ice collision problem is proposed, and the material model is verified. The simulation results in this paper are in good agreement with the ISO theoretical curves and the experimental data. It is proved that the model can be used in the numerical simulation of the sandwich plate and ice collision problems. At the same time, it is applied to the collision simulation of ice body and sandwich plate. The collision force and energy absorption of traditional plate structure and metal sandwich plate under ice load are compared. The impace resistance factors composed of impact positions and ice body shapes is analyzed, that provide a reference for the application of the new sandwich plate provides a reference.
