摘要

The paper deals with a frictionless contact problem of two congruent rigid spherical surfaces, one encased in the other, coated with a thin elastic transversely isotropic and incompressible bonded layer. A simplifying approximation for the displacement in the coating enables the problem to be formulated using stress and strain averaged through the coating thickness (for the method see M. J. Matthewson, Journal of Mechanics and Physics of Solids 29 (1981), 89-113). Analytical results are obtained for the contact radius and the contact stress distribution. Given this contact stress distribution, an asymptotic analytical solution for the displacement in the coating is then obtained, The results are applied to the human hip joint.
