An analytical approach based on certain assumptions regarding the character of the kinematic relations and equilibrium conditions was developed to calculate the stress-strain state of naturally twisted rods of composite materials. A computer program for calculating the stress and strain parameters in each layer was also developed. The results of calculations performed in accordance with the linearized variant (Eq. (5)) of general relations (4) agree satisfactorily with experimental data within a broad range of acting longitudinal loads. The method that was developed has been widely used in the design and optimization of several types of structures.
