ABSTRAKT

Equations for the definition of beam stiffnesses, positions of neutral axes, and rotation centers at bending and torsion, stresses, and deformations of a composite wing with an anisotropic skin are obtained based on the classical beam theory. A comparison of the results obtained from the analytical solutions and the results obtained from the finite-element computations is performed.
