报告摘要
The problem of forced unsteady water waves under an elastic sheet is a model for waves under ice or under very large floating structures. Even though small-amplitude solitary waves are not predicted to exist by standard perturbation analyses, we find large-amplitude solitary waves and explore their crucial role in the forced problem of a moving load on the elastic cover. This phenomenon is very much like vibrations of fast train tracks and meant to represent a model of the use of extended ice sheets as roads and aircraft runways. Both numerical and theoretical results will be discussed in the talk, and some unsolved problems will be mentioned in the end.
