Abstract


A criteria of ice sheet fracture by propagating waves is proposed based on an elastic bending theory. Experiments with a model ice are carried out to examine the validity of the criteria. Comparisons with experimental results show that the proposed criteria is available for a wide range of ice properties. The crack span induced by waves is between 1/4 and 1/2 of wave length in ice.
