| Abstract |
The present paper deals with the solution of the boundary value problem on a plastic layer flow between rigid plates approaching each other in A. A. Il'yushin's setting. After averaging over the layer thickness, the problem is reduced to a two-dimensional spreading problem for a domain with free boundary occupied by a plastic medium.
The plastic medium material in such a flow is well described by the viscous fluid model. But the solution obtained earlier holds only in the perfect fluid approximation. It is shown that this solution does not satisfy one of the dynamic conditions on the free boundary of the domain.
A sound analytic study of the boundary value problem is performed in the paper. The boundary layer is used to obtain a solution satisfying all boundary conditions. If the flow described by perfect fluid is directed along the normal to the boundary, then it also has a tangential velocity component in the boundary layer. Moreover, the obtained velocity field is used to derive the evolution equation for the free boundary. It is shown that, for a sufficiently smooth boundary, this equation coincides with the equation obtained earlier. |
