| Summary: | Introduction Reference [1] presents the plane-wave impulse of a laterally compressed floating elastic plate. The method used to derive this solution is basically that of Greenhill The plane-wave impulse response contains all of the admissible characteristic values for the linear floating plate, and, ideally with superposition it is possible to solve any particular problem. However, because the Greenhill [2] formulation does not include bending losses in the plate, quantitative deflections of a specified ice sheet by a given moving vehicle cannot be obtained from the lossless impulse response. The deflection under a moving vehicle is strongly dependent upon the growth rate of the excited gravity waves, a factor that in turn depends critically upon the loss rate |
