Stability and Post-Buckling Behavior of Orthotropic Cylindrical Shells With Local Deflections

A procedure for analytical solution of the problem of the stability and post-buckling behavior of orthotropic cylindrical shells under external pressure or axial compression with allowance for transverse shears is developed. The shells are geometrically imperfect due to the presence of a local deflection. The problem is solved by analyzing the interaction of the modes that represent the critical loads of the perfect shell and using the Byskov–Hutchinson method. Equilibrium curves for both shells are plotted using the method of continuous loading
