Abstract Ship-ice interaction is an important engineering issue in the polar region. Choosing the appropriate sea ice simulation method in the simulation of ship-ice collision will have a greater impact on the collision force of the ship hull. Sea ice is a complex solid. If you want to truly Simulating actual sea ice properties presents significant challenges. In order to more accurately simulate the interaction of ship ice in actual navigation, this study uses the nonlinear explicit finite element method for calculation, and establishes a sea ice calculation model based on the piecewise linear plastic constitutive model. The cohesion is used as a calculation method for sea ice fracture, the hull uses an elastic-plastic constitutive model, and the ALE method is finally used to solve the complex fluid-solid coupling problem of the ship, water, and ice phases. By comparing the simulations of cohesive models with the same parameters and hybrid parameters, the calculation results show that during the ship ice fluid-solid coupling calculation process, the hybrid cohesive simulates the circumferential and longitudinal crack forms of sea ice better, and the ice load is consistent with The hull stress is closer to the empirical formula. This study provides a useful reference for improving ice operations and offshore structure design in Arctic shipping, and has great research significance for improving ship performance and safety.
