Ice crushing occurs in many situations that involve a sliding frictional component such as sports involving ice-contact, ice interaction with ship hulls, and ice-on-ice sliding/crushing within glaciers and between interacting sea ice floes. Ice crush

Data from ice impact tests using a large double-pendulum apparatus have been analyzed and high spatial resolution pressure-pattern images, recorded at rates of 500 images per second, are presented. The freshwater ice samples were grown in the lab and

In discussing ice crushing in the brittle regime Gagnon (2016) had speculated that small Tyndall melt figures, functioning in conjunction with a previously observed thin squeeze-film slurry layer of melt and ice particles at the ice/structure interfa

Ice crushing occurs to varying degrees in many situations including those that involve a sliding frictional component, such as in sports involving ice contact, ice interaction with bridges, piers, ship hulls, vehicle wheels, rock beds under glaciers

The structural hull response of a ship or offshore structure to moving (or sliding) loads has been shown to be significantly different than that of stationary loads of the same magnitude; when those loads cause plastic damage. A standard hull grillag

The ice crushing induced vibration and so-called lock-in behavior exhibited by the Molikpaq structure during a test case event that occurred on May 12, 1986 has been explained in terms of ice spalling, and associated sawtooth load and displacement pa

Numerical simulations of a collision between a loaded tanker and a bergy bit have been conducted using LS-Dyna™ software. The simulations incorporated hydrodynamics, via LS-Dyna's ALE formulation, and a validated crushable foam ice model. The major
