Abstract

The stress state of a soft interlayer under contact strengthening, when tensile stresses are greater than the yield strength, and less than the stresses causing a genetal yield, is consi­dered. The analytical expressions under plain strain and axisymmetric tension are obtained. In the first case the stresses are determined using the Airy stress function as a correspon­ding polynomial, in the second case – based on the stress function of the fifth degree, built on the corresponding Legendre polynomial. The stresses satisfy the differen­tial equations of equilibrium and boundary conditions.
