... properties of level ice fields and ridges. The first type of experiments of sea ice breaking on the selected polygon of level ice, were carried out under the scenario of cyclic loads from the icebreaker. Due to the ice cover bending during the break, elastic longitudinal, elastic transverse and flexural...
