Abstract: The crushing and failure of level ice against conical structures is a typical problem in studies of ice–structure interaction, and reliable prediction of ice-induced loads and impulses is important for the safety assessment of polar engineering structures. To address the limited applicability of existing models in predicting the upper bound of impulse and associated loads, a new compressive strength formulation for ice is developed based on a series of uniaxial compression experiments conducted by the authors. The proposed formulation is implemented into a numerical discrete element model (NDEM) and applied to simulate the crushing process between level ice and a conical structure. By comparing the numerical results with data from original physical experiments, the accuracy and applicability of the proposed formulation in predicting ice-induced loads during ship–ice collision simulations are verified, and provides a valuable reference for future numerical modeling of ice–structure interactions.
