Ship waves on an elastic floating ice plate

Wave wakes produced by a finite-size source uniformly moving on an ice plate overlying deep water is studied. The kinematic and amplitude characteristics of source-generated flexural-gravity waves are presented in terms of isophase patterns; the wave patterns are determined by ad hoc defined analogues of Mach and Bond numbers. The Reference Solution Approach is used to describe the distribution of wave amplitudes in the wake accounting for the source size and shape. This approach agrees with the Stationary Phase Method in the far-field zone and reproduces also specific wave dynamics at short and intermediate distances from the source.
