摘要

This paper focuses on the stability analysis of delaminated cylindrical shells. The static and stability analyses of cylindrical shells are carried out to validate the finite element developed by the authors in dealing with shell structures. Examples on the stability of delaminated isotropic and orthotropic cylindrical shells are studied. The critical buckling force and the buckling mode are obtained for different delamination sizes. The results obtained in the present study are compared with those in literature. Three buckling patterns, i.e. the local, mixed and global modes, are observed for the delaminated cylindrical shells.
