Composite cylindrical shells are already commonly used in structural engineering, and their buckling is of vital importance in the design of such structures. The linear eigenvalue problem can be used as an initial analysis method due to the huge discrepancies observed between test results and theoretical predictions, and one can choose the geometrically nonlinear analysis for further study. The one-third composite cylindrical shells with cover were chosen as research object loaded in compression, and an ABAQUS finite element model was built at first. A linear eigenvalue analysis based on Buckle algorithm and a geometrically nonlinear post-buckling analysis based on Riks algorithm are developed for this research. The strain and load numerical results were matched well with test results. The Riks analysis shows that the structure has the post-buckling carrying capacity and can also reach a stable nonlinear equilibrium path, grasping the critical buckling load accurately, and the buckling modes are more close to the test ones. Therefore, it is more reliable to take the result based on geometrically nonlinear Riks algorithm as design criteria. A general geometrically imperfection sensitivity analysis is performed. The study shows that the cover shell is sensitive to imperfection, and we should improve the quality of processing and reduce the initial geometric imperfection in order to enhance stable performance.
