The Newton-Raphson approach as well as the arc-length approach is used to ensure the correctness of the equilibrium paths up to the limit point load. Post-buckling behavior of imperfect cylindrical shells with different L/D and R/t ratios of interest is obtained and the theoretical knock-down factors are reported for the considered cylindrical shells. %K Post-Buckling %K Cylindrical Shells %K Eigen Imperfection Shapes %K Axial Compressive Load %K Bending Load %K Torsion Load %K Arc-Length Method %K Knock-Down Factor %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=60978
