Ice forces on an isolated circular pile

This paper presents a mathematical model for calculating the forces that a moving ice cover will exert against an isolated pile. The model requires knowledge of the relationship between strain rate in the ice and the rate at which the ice cover is moving relative to the pile. An experimental and a t...
