A Numerical Model Of Ice Crushing Using A Foam

A spectral model for forces due to ice crushing journal This paper presents a model of dynamic ice forces on vertical offshore structures The model concerns a loading scenario where a competent ice sheet is drifting and crushing against the structure Full scale data obtained on two offshore structures were used in the derivation of a method that applies both to narrow and wide structures
