Abstract
Contact interaction of hard stamps with angular points and massive elastic bodies with circular cylindrical holes is investigated in this article. Refined interaction model considers the initial difference of curvature of contacting surfaces and features the transfer of torque from stamps to an elastic body by friction forces, which are set by Kulon’s law. Based on the expressions for displacement of contour points of elastic body, the system of singular integral equations with logarithmic kernels was created. Solution of the equation system allows to determine the position and size of the contact zone, stress-strain state on the border of elastic body and value of clamping force in the system of stamps, which ensures the maximum torque transmission and ensures minimum crushing of material. Depending on the ratio between the curvature surfaces of contacting bodies, different options of interaction are analyzed.
