Entry and exit of an elastic shell on a thin layer of the water

Khabakhpasheva T.I.

Lavrentyev Institute of Hydrodynamic (Novosibirsk)

The paper is concerned with a problem of elastic shell fall down onto a thin layer of an ideal incompressible liquid. The shell initially touches the liquid free surface at a single point and then penetrates the liquid layer. The problem is coupled because the liquid flow, the shape of the elastic shell and the geometry of the contact region between the body and the liquid must be determined simultaneously. The 2D-problem of a circular cylindrical shell impact and axisymmetrical case were considered before by the method of matched asymptotic expansions for analyzes of liquid flow. This method was developed by Korobkin (1995) for the case of the flat rigid body penetrate onto a the thin layer of the liquid. The structural analysis is based on the normal-mode method. Strain-time histories of the inner surface of the spherical shell are of particular interest. At the present study velocity of the interaction is small and effects of gravity taken into account. It is allow us to considered not only exit, but also exit of shell from the water layer under the buoyancy forces.
