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… 

Establishing buckling loads for axially compressed composite cylindrical shells based on energy barrier approach

Abstract Due to the well-known geometric imperfection sensitivity, how to design a composite cylindrical shell with both adequate buckling load and lightweight characteristic is still a challenging

IMPROVED METHODS FOR MODELLING IMPERFECTIONS FOR BUCKLING ANALYSIS OF COMPOSITE CYLINDRICAL SHELLS

There is a substantial requirement for more robust, lighter and cheaper launch vehicle structures. Essential to the fabrication of launch vehicle airframes are unstiffened composite shells, which are

The Effects of Geometric and Loading Imperfections on the Response and Lower-Bound Buckling Load of a Compression-Loaded Cylindrical Shell

Results from a numerical study of the buckling response of a thin-walled compression- loaded isotropic circular cylindrical shell with initial geometric and loading imperfections are used to

Investigation of Buckling Behavior of Composite Shell Structures with Cutouts

Thin-walled cylindrical composite shell structures can be applied in space applications, looking for lighter and cheaper launcher transport system. These structures are prone to buckling under axial
