Global Ice Forces and Ship Response to Ice
During September and October of 1985 the Polar Sea conducted ice impact tests on heavily ridged ice features in the Alaskan portion of the Beaufort Sea. Bending strain gage measurements were used to estimate the longitude bending moment distribution of the Polar Sea during impacts with ice pressure...
