ABSTRACTSeveral definitions of equivalent ice thickness for simplification of complex ice cover are found in the literature. However, their systematic analysis is currently absent. Therefore, this ...

Abstract As aqueous model ice is used extensively in ice tanks tests on the performance of ship hulls in sheet ice, it is imperative that such model ice replicate the main flexural strength behavior of sheets of sea ice and freshwater ice. Ice tanks use various types of aqueous model ice types, each of which contain brine dopants to scale-reduce ice-sheet strength. Dopants, though, introduce non-linear trends in the scaled flexural behavior of model ice sheets, and can affect ice loads and ice-r...

The database contains data from analyzed cantilever bending strength experiments with respect to their non-linear behavior. Additionally, data on the composition of the tested model ice sheets (chemical dopants, grain structure, etc.) are listed.

Abstract Ice material models often limit the accuracy of ice related simulations. The reasons for this are manifold, e.g. complex ice properties. One issue is linking experimental data to ice material modeling, where the aim is to identify patterns in the data that can be used by the models. However, numerous parameters that influence ice behavior lead to large, high dimensional data sets which are often fragmented. Handling the data manually becomes impractical. Machine learning and statistical...

ABSTRACTShip collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. Experience on the conditions of shared-energy collision tests is limited. The aim of this paper is to present an experimental study on a scenario where the impacted structure undergoes permanent deformations together with ice failure. The paper describes a series of ...
