Abstract: The discrete element method is capable of analyzing multiple, interacting, deformable, discontinuous or fractured bodies undergoing large motions and rotations. The formulation solves the dynamic equilibrium equations with a set of decoupled orthogonal modal equations for each element in which elements communicate through boundary forces. The objective of the project was to validate the model for a variety of ice-structure interaction behavior; namely, ice ride-up and pile-up, ice ridge-conical structure interaction, pier-ice sheet indentation, and dynamic multi-year floe impacts against Hans Island. The intent of the Phase I portion of the project involving validation of the model for ice ride-up and ice ridge conical structure interaction is described. The two experimental data sets selected for validation purposes are ice ridge conical structure interaction of a 1/17 scale prototype and ice ride-up and ice pile-up on two beach configurations in the Esso test basin.
