WebMar 1, 2011 · In this study, application of the proposed ice model is limited to iceberg impact scenarios. Contrary to sea ice, iceberg ice may reasonably be considered as isotropic (Sanderson, 1988). The temperature and strain rate influence on iceberg strength are discussed. The difference in strength between the tensile and compression states …
