Abstract : A functional model is proposed to predict the deformations induced in an elastic structure by the impact of a free falling blcok of ice. The initial shock, assumed to be of plastic nature, causes extensive cracking in the ice block. The subsequent contact forces are then neglected and the motions become uncoupled. The proposed analytical relationship is verified by experimental data involving 58 impact tests on two model structures of different rigidities. (Author)
