Description
Summary:Using the asymptotic theory, explicit analytical expressions were obtained that allow one to calculate the stress-strain state of multilayer thin cylindrical anisotropic elastic composite shells for small deformations. Forenamed expressions allow us to obtain the distribution of all components of the stress-strain state without any assumptions about their nature of the distribution over the thickness. An algorithm was proposed that makes it possible to obtain the total stress tensor in the shell, and all components of the stress tensor are numerically calculated for the case of a cylindrical composite shell with axisymmetric bending by pressure. The character of the distribution of characteristics of the stress-strain state of the shell was analyzed and the corresponding graphs were constructed.
