摘要：
An interaction of the moving submerged circular cylinder with elastic solid ice cover is investigated. The method of reduction to integral-differential system of equations is extended to the case of elastic ice sheet floating on the fluid surface. The elastic properties of the ice are accounted for by the Euler's beam theory. A special iterative procedure is developed to construct small-time asymptotic solution for the cylinder moving with constant acceleration from rest. Elastic-gravity waves in the ice cover are studied in a wide range of parameters.
