Dynamics of the elastic ice sheet
In the process of ice-structure interaction, elastic waves propagate outward from the contact points into the depth of a moving infinite ice sheet carrying away with them a certain amount of energy.Although the equations of motion do not contain dissipative terms the damping effect occurs due to the...
