Title On an Ice Failure Model with a Large Contact Region

Abstract An ice failure model with large force contact region is presented. This model is based on survey and analysis of field and experimental observations and assumes the existence of a quasi-regular failure structure in the contact region, where the failure nucleus can move on the contact surface (scan it). The character of motion is determined by the conditions of the failure nucleus displacement and the failure product extrusion from the contact region. The mechanism ensuring the average stress decrease as the contact region increases is explained.
