Abstract
The problem of the contact deformation of a friction couple bushing is discussed. It is assumed that the bushing has an arbitrary number of rectangular cracks near the friction surface. They have boundary areas within which the cracks interact. The boundary value problem of the equilibrium of the friction couple bushing with cracks interacting along the edges is tackled by solving the system of nonlinear singular integrodifferential equations with a kernel of the Kochi type. The solution of this system of equations has yielded the normal and tangent forces in the interface. The condition of the limiting equilibrium of the crack with the boundary regions is formulated by taking into account the criterion of the limiting stretching of the material’s bonds.
