Influence of the Mechanical and Geometric Parameters of Composite Cylindrical Shells with Local Deflection on the Behavior of the Equilibrium Curves Under Axial Compression

Abstract

A procedure for analytical solution of the problem of the stability and post-buckling behavior of composite cylindrical shells with local deflection under axial compression is developed. The algorithm is developed based on the Timoshenko–Mindlin nonlinear shell theory and Byskov–Hutchinson asymptotic method. The dependence of ultimate loads and equilibrium curves on the mechanical and geometric characteristics of the shells and laminate structure is studied.
