The Fracture of Sea Ice


This paper describes investigations directed towards the identification of an appropriate fracture parameter for sea ice. It is concluded that for laboratory sized specimens, LEFM is not suitable for characterizing the fracture of warm sea ice. A cohesive crack approach is used to model the nonlinear load vs displacement behavior observed experimentally. The fracture of sea ice is characterized by the fracture resistance curve KR.
