Development of a Viscoelastic Finite Difference Formulation for Analysis of Ice Sheet - Structure Interactions.
This work reviews two models of ice sheet interaction with a particular structural shape, an isolated circular pile. A new model is developed using classical small element elastic theory. The ensuing equations are reduced by an adaptation of circular symmetry from a plane stress, two-dimensional rep...
