The unbounded normal stress of a contact problem for a cylinder

Abstract
The contact problem of symmetric indentation of two punches in the form of circular segments, without friction, into the
exterior surface of a cylinder under harmonic force P0 cos !t is considered. The problem is formulated into a singular integral
equation of Hilbert type, its solution providing an expression for the physically important unbounded normal stress. For the
sake of completing the definition of this expression, the integral equation is converted into an infinite system of algebraic
equations the solution of which can be obtained by means of the method of truncation. The truncation is justified and the error
is estimated.
