The article is devoted to the research of problems of contact interaction of infinite elastic stringer with
two identical clamped along one edge of pre-stressed strips. In general, the research was carried out for the theory
of great initial and different variants of the theory of small initial deformations within the framework of linearized
theory of elasticity with the elastic potential having arbitrary structure. The integral integer-differential
equations are obtained using the integral Fourier transform. Their solution is represented in the form of quasiregular
infinite systems of algebraic equations. In the article alsaw was investigated the influence of the initial
(residual) stresses in strips on the law of distribution of contact stresses along the line of contact with an infinite
stringer. The system is solved in a closed forms using transformation of Fourier. Expressions of stresses are represented
by Fourier integrals with a simple enough structure. Influence of initial stress on the distribution of contact
stresses is study and discovered the mechanical effects under the influence of concentrated loads.
