APPROXIMATE SOLUTION OF AN AXISYMMETRIC CONTACT PROBLEM WITH ALLOWANCE FOR TANGENTIAL DISPLACEMENTS ON THE CONTACT SURFACE

摘要

A structurally nonlinear contact problem of a punch shaped like a paraboloid of revolution is studied. An equation for the contact-pressure density is derived, with allowance for the radial tangential displacements of the boundary points of an elastic half-space. A method for constructing a closed-form approximate solution is proposed. The. effect of the tangential displacements on the main contact parameters is discussed.
