摘要：
An approach to solving spatial problems of the stress-strain state and stability of layered anisotropic cylindrical shells is developed. The anisotropy is characterized by one plane of elastic symmetry. The numerical implementation of the approach is based on the combination of the Bubnov-Galerkin, discrete Fourier transform, and discrete-orthgonalization methods. The results obtained are in good agreement with the solutions of simpler problems. A new stability problem for a sandwich shell is solved.
