... (or the contact conditions) as well as the complicated repetitive ice load. This repetitive ice breaking process due to bending is not well known because of the complexity of the geometry of the broken ice pieces. The ice breaking process consists of two phases: the dynamic bending of ice sheet...

... considered three components of ice loads on a conical structure. They are a component tobreak the ice (the breaking component), component due to rotation of broken ice piece (the foundation component) and component due to ice pieces riding up onto the cone (the ride-up component). However, he assumed...

... are identified. The effects of the rubble field on the Ice force are shown to be a function of ice piece size, the ice strength and ice thickness. Based on these tests, the rubble can Increase the Ice load by a factor of two to three. The largest relative increase in load due to rubble occurs for thinner, weaker...
