Abstract: | A contact problem for an infinitely long hollow cylinder is considered. The cylinder is compressed by an outer rigid ring
with a circular profile. The material of the cylinder is linearly elastic and isotropic. The extent of the contact region
and the pressure distribution are sought. Governing equations of the elasticity theory for the axisymmetric problem in cylindrical
coordinates are solved by Fourier transforms and general expressions for the displacements are obtained. Using the boundary
conditions, the formulation is reduced to a singular integral equation. This equation is solved by using the Gaussian quadrature.
Then the pressure distribution on the contact region is determined. Numerical results for the contact pressure and the distance
characterizing the contact area are given in graphical form.
