| Abstract: | Nonlinear hydroelastic waves travelling at the surface of an ideal fluid covered by a thin ice plate are presented. The continuous ice-plate model is based on the special Cosserat theory of hyperelastic shells satisfying Kirchoff's hypothesis. Two-dimensional solitary waves are computed using boundary integral methods and their evolution in time and stability is analysed using a pseudospectral method based on FFT and in the expansion of the Dirichlet-Neuman operator. Extensions of this problem including internal waves and three-dimensional waves will be considered.
When the ice-plate is fragmented, a new model is used by allowing the coefficient of the flexural rigidity to vary spatially. The attenuation of solitary waves is studied by using two-dimensional simulations. |
