A contact problem is studied for a prestressed elastic strip with an elastic reinforcement. The integral
Fourier transform is used to construct an influence function for an infinite strip with one face fixed. A
unit concentrated force is applied to the strip at an arbitrary angle. The contact problem on force
transfer from a thin infinite stringer to the prestressed strip is solved. The problem is mathematically
formulated as a system of integro-differential equations for the unknown contact stresses on the
assumption that the beam bending model and the uniaxial stress model are valid for the stringer, which
is subjected to both vertical and horizontal forces. This system is solved in a closed form using the
integral Fourier transform. The contact stresses are expressed in terms of Fourier integrals in a quite
simple form. The influence of the initial stresses on the contact stress distribution is analyzed, and effects
of concentrated load are revealed.
