Analysis of Calving Events in Antarctic Ice Shelves Using Configurational Forces
Abstract Previous studies on the sensitivity of cracks in ice shelves with different boundary conditions, stress states and density profiles revealed the need for further analyses. As the transfer of boundary conditions from dynamic ice flow simulations to the linear elastic fracture analyses proved...
