Friction of sea ice on various construction materials
A series of tests was performed at the Canadian Hydraulics Centre to investigate friction between sea ice and various materials such as concrete, steel, wood and ice. The tests examined the effects of the change in the friction coefficient corresponding with the deterioration of material surface, sp...
