Deceit

Mechanisms of Cyclic Strengthening and Recovery of Polycrystalline IceStrengthening and subsequent recovery of relatively warm polycrystalline ice cyclically loaded is attributed to a dynamic competition between the buildup of an internal back stress that originates either from dislocation pileups or grain boundary sliding and a process of creep-driven stress relaxation.

Source Location and Dataset Incompleteness in Acoustic Emissions from Ice Tank Tests on Ice-Rubble-Iation of the AE activity. Secondly, we investigate the possibility of incompleteness in the AE datasets during periods of increased activity. Our results from source location show that the round rubble geometry gave higher acoustic activity at the sliding interfaces. We observe potential incompleten

The Influence of Ice Rubble on Sea Ice Friction: Experimental Evidence on the Centimetre and Metre Sion, we find that when floes are in static contact for a short time, the presence of rubble acts to reduce static friction. However, if floes and rubble remain in static contact for around 10. s (a few hours) then the presence of rubble promotes strengthening, and the floe-floe effective friction ca

Ice Action on Ship Hull: What Do We Know and What Do We Miss? give information about the load patch and total maximum force. In the last chapter some ship measurements are described. These have mostly endorsed the observed ice load magnitude and also the small load height of the load patch. The aim of the paper is to give an insight of how the ice action on s
