Thin-walled shell structures prone to buckling are sensitive to imperfections. The influence of loading and geometrical imperfections on buckling loads of unstiffened composite cylindrical shells is investigated based on tests and computations. It is shown that their effect depends on laminate set-up. The results show that unification of imperfection sensitivity is allowed; systems sensitive to geometrical imperfections are also sensitive to loading imperfections. The results can be used to… Expand
