Effective Tensile Strength of an Ice Sheet Using a Three-dimensional FEM-DEM Approach

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 appl...
