| Abstract |
The tree-dimensional problem of equilibrium of an elastic wedge whose surfaces are reinforced (with complete adhesion) by thin plates which are rigid in tension but perfectly flexible. The problem is symmetric with respect to the bisecting half-plane of the wedge. The plates are subjected to prescribed tangential forces. The desired quantities are the tangential stresses in the contact region, translational displacement, and angle of rotation of a plate. The relations that enable one to calculate completely the displacement vector and stress tensor in the three-dimensional elastic wedge whose surfaces are subjected to symmetric tangential loads directed arbitrarily are presented. These relations generalize the solutions obtained in [1-3] in which the tangential load is perpendicular to the edge of the wedge. With the aid of two Green's functions obtained, the contact problem is reduced to the system of two integral equations for the tangential stresses. In the case of elliptic plates, this system is solved by using the regular asymptotic method. As the zero term of the asymptotic relation, the exact solution of a similar problem for plates on the elastic half-space [4] is used. Numerical examples are presented.
For two-dimensional contact problems with friction and adhesion, asymptotic methods were used in [5, 6]. |
