Abstract

A sea ice sheet may fail through several mechanisms when interacting with an obstacle. Susceptibility and mode of failure behave as functions of the physical size of a sheet. In this paper we compute the effective uniaxial tensile strength of an ice sheet for several different specimen sizes by applying a three-dimensional combined finite-discrete element approach. We evaluate the effect of the loading rate by using two displacement rates. Although a rate-independent cohesive formulation is used and the displacement rates applied are low, a significant rate effect emerges.
