Abstract : The equilibrium stability of an orthotropic cylindrical shell is examined from the standpoint of three-dimensional linearized equations. For shells made of materials with low shear stiffness, such an approach allows one to take into account precisely (within the framework of small subcritical deformations) the influence of the properties all the material on the value of the critical stress. Questions on the asymptotic accuracy of the hypothesis of plane sections for a rod with circular cross section and the Kirkhgofa-Lyava hypothesis for a plate and a transversal-isotropic shell have been examined.
