On the Scalability of Model Scale Ice Experiments

Abstract

Ice model tests are a frequently used mean to assess and predict the performance of ships and structures in ice. The model ice composition is adjusted to comply with Froude and Cauchy similitude. Recent research indicates that the internal mechanics of Aalto modelscale ice and sea ice differ significantly. This consequently limits the scalability and challenges stateoftheart scaling procedures. This paper presents a qualitative assessment on selected topics to assess the differences between modelscale ice and sea ice and the influence of related experiments on determined mechanical properties. Furthermore, existing scaling approaches are discussed in context of recent research findings.
