LARGE DEFORMATION, DYNAMIC, PLANE STRESS ANALYSIS OF ICE-STRUCTURE INTERACTION

In this paper, the interaction of an ice sheet with an off-shore pile, such as in the support structure of a drilling platform or a docking facility, is considered. The pile is treated as a rigid member and the ice sheet is assumed to be subjected at its periphery to horizontal time-varying distributed loads. The problem is treated as a dynamic plane stress problem. The numerical solution of this model, using a large deformation computer code (CIRKICE) based on the method of artificial viscosity, yields complete stress fields in the ice sheet and the forces experienced by the pile. This information is useful both in designing the structure and in studying the problem of 'ice breakup.'
