1.Introduction. Ice is an extremely brittle material. Yet at very low loading rates, ice creeps, dissipating energy mainly as heat. This is not a result of the loading rate per se, but rather the result of the fact that the creep process keeps the load, and consequently the strain-energy density, at a level low enough to preclude fracture.Once this density exceeds a critical value, …
