An energy model for ice crushing in ice-structure impact
When a steel structure meets ice in impact like contact, the ice is being crushed at the location of the contact. In this paper, the energy loss related to the ice crushing is implemented to a contact load model. Then, the effect of energy loss on simulated ice-structure contact load is studied and...
