Abstract
The dynamic friction of ice can be estimated by
thermodynamic models. The authors have developed a
thermodynamic ice friction model, which is summarized in
this paper. This model can be applied to dynamic friction
between ice and some other material, and to ice-ice
friction. The model has been successfully verified by
laboratory experiments using freshwater ice. Here, we
discuss the applicability of this model to sea ice
friction and use it in explaining ice friction
measurements presented in the literature for saline ice.
We identify the discrepancies and develop the model
accordingly. The improved model can be used, instead of a
fixed friction coefficient, in estimating friction on a
vessel navigating in ice and in modelling sea ice
dynamics and ice crushing processes.
