DIMENSIONLESS STRENGTH PARAMETERS FOR FLOATING ICE SHEETS

The problem of vertical loadings on floating ice sheets is discussed from the standpoint of dimensional analysis. Important dimensionless parameters are identified, and strength parameters are considered in detail. Two example problems are studied. One involves the question of the height to which ice will pile against a sea wall. This problem is directly related to the question of the maximum height of pressure ridges. Rafting serves as a second example. The maximum thickness of ice which will raft is found to depend on the square of the strength. The results show how scale experiments can be designed to yield data applicable to full scale problems. The dimensional parameters also provide an efficient means of presenting either analytical or experimental data.
