The article deals with circular cylindrical shells of arbitrary length, which are regarded as structurally anisotropic. The problem of stability is solved by the energy method. Hypotheses of the absence of shears in the middle surface and other inextensibility of the contour of the cross section were adopted. The expressions for the critical loads as functions of the parameters of wave formation with an axially symmetric initial state of the shell were obtained from a solution of the equation of Euler's variational problem. Note is taken of weakening of the effect of the influence of eccentricity with an increase in the length of the shell.

The paper considers the phenomenon of stability loss in shells with an arbitrary generatrix curvature due to the effects of axial compression and radial pressure. The problem is solved by the energy method, making use of certain derivations from the author's earlier work. To illustrate the unquestionable applicability of the proposed method, the paper presents, in addition to solutions of new problems, the derivations of certain working formulas available in the literature, specifically for a sphere and an ellipsoid of revolution loaded by an excess radial pressure. The problem of stress concentration around a round hole in an orthotropic cylindrical shell is solved by the Bubnov-Galerkin method, proceeding from the relationships of the general theory of the orthotropic cylindrical shell referred to a polar semigeodesic coordinate system. Together with the variational equation, the boundary conditions are brought to the form of a system of algebraic equations that can be programmed and solved on an ETsVM. As an example, the influence of anistropy on stress concentration around a round hole in an orthotropic cylindrical shell acted upon by a uniform axial compression is considered.

One of the most important problems in the design of engineering structures is the determination of the carrying capacity of a structure. A component element of this problem is the calculation of critical stresses during the action of compressive loads. The present work, devoted to the stability of framed circular cylindrical shells, is the first of three articles, in which an attempt is made to solve the problem of calculation of the carrying capacity of the indicated structures.
