    Abstract

    In this paper we simulate a punch through test of partly consolidated ice ridge keel with three dimensional discrete element method. We model the contact forces between discrete ice blocks with Hertz-Mindlin contact model. For freeze bonds between the ice blocks we apply classical linear cohesion model with few modifications. In simulations we vary the parameters that are most relevant to maximum force on indenter and examine the causalities due to variation. In addition, the failure mechanisms in ice rubble are studied. We compare the simulation results to full-scale experimental results to confirm the feasibility of the model. The results show that the simulations are in excellent agreement with the previous results. Based on simulations, we are able to determine the main characteristics of an ice ridge from material parameters of ice and freeze bonds. Furthermore, we conclude that the model introduced can be used in other applications within ice mechanics.
