Abstract

The stability of fiber-reinforced cylindrical shells under torsion is analyzed in the case where the principal directions of elasticity in the layers do not coincide with the coordinate directions. The solution to the linearized equations of the technical theory of anisotropic shells is obtained in the form of trigonometric series. It is shown that for some reinforcement configurations the critical loads may depend on the direction of the torsional moment. It is also established that the minimum (in absolute value) eigenvalue does not always correspond to the critical load. This fact should be taken into account not only in the case of torsion but also in more complicated cases of loading
