- W4316369176 abstract "We develop a phase-ï¬eld model of brittle fracture to model fracture of sea ice ï¬oes. Phase ï¬elds allow a variational formulation of fracture using an energy functional that combines a linear elastic energy with a term modeling the energetic cost of fracture. We study the fracture strength of ice ï¬oes with stochastic thickness variations under boundary forcings or displacements. Our approach models refrozen cracks or other linear ice impurities with stochastic models for thickness proï¬les. We ï¬nd that the orientation of thickness variations are an important factor for the strength of ice ï¬oes and study the distribution of critical stresses leading to fracture. Potential applications to Discrete Element Method (DEM) simulations and ï¬eld data from the ICEx 2018 campaign are discussed." @default.
