The paper considers the problem of determining deflections in the inhomogeneous composite rod, which certain cross section parts consist of materials with different physical and mechanical properties. It proposes a solution to introduce the reduced stiffness depending both on the section part geometric parameters and on properties of the corresponding materials, as well as a certain Mohr integral generalization for the indicated resistance case. It is noted that this model is not accounting for the contact interaction effect in contact zones of the rod various components. The paper analyzes practical application of the proposed solution. To assess accuracy of the proposed solution, a finite element computation was carried out in the Compass-3D software package.
