For various structures in the ice infested waters, ice force acting on them is one of the main concerns. From the mechanics point of view, ice–structure interaction is a process involving structure mechanics (or dynamics) and failure mechanics of ice as a solid material. Structure analysis under external loads has become quite handy after decades of research and practice, unfortunately on the other hand, fracture mechanics or damage mechanics is not able to quantify the failure behaviors of ice acting on structures, mainly because of the extremely complex mechanical behavior of ice (Sanderson, 1988). As a result, ice forces cannot be predicted accurately using analytical or numerical methods, and conducting tests is necessary to obtain enough real information about ice forces and corresponding structure responses.
