Impact of Testing Method on Measured Flexural Strength of Model-Scale Ice
Ice-going vessels and offshore structures designed to break ice in bending rely on the reported flexural strength of ice. Depending on the ice conditions, the flexural strength can be affected by the choice of testing method. Nonetheless, the International Towing Tank Committee (ITTC) recommends thr...
