In this paper a multi-mode finite element implementation of Koiter's initial post-buckling theory with the inclusion of the pre-buckling nonlinearity is presented. Using this implementation a multi-mode initial post-buckling analysis of an axially loaded composite cylindrical shell has been carried out with a small number of representative modes. The implementation has been done in a general purpose finite element code. Results are compared with results from semi-analytical perturbation
