Contact Problem for the Rigid Ring Stamp and the Half-Space with Initial (Residual) Stresses.

The problem of the contact interaction of a rigid cylindrical ring punch and half-space with initial (residual) stresses is considered disregarding the friction forces in the case of unequal roots of the characteristic equation. The study is performed in common form for the theory of large (finite) initial deformations and two variants of the theory of small initial deformations within the framework of the linearized theory of elasticity for arbitrary elastic potential. The numerical results are presented in the form of graphs for Treloar's potential. [ABSTRACT FROM AUTHOR]
