Resonance method of ice destruction
The Resonance method of ice destruction means breaking sheet-ice which has formed over a body of water by causing the ice and water to oscillate up and down until the ice suffers sufficient mechanical fatigue to cause a fracture.
==Resonance==
If static force is applied to a sheet of ice it will flex slightly before suffering a catastrophic failure. Since the ice will bend slightly when any vehicle capable of travelling on ice-covered water, it follows that travelling at some critical speed may to impose sufficient flexing of the ice sheet to cause resonance, and this may result in positive feedback effectively amplifying the oscillation within the body of water supporting the ice beneath the vehicle.
