• The shear properties of composite laminates are expected to degrade significantly due to interlaminar delaminations as the compressive properties. The shear buckling and postbuckling behaviors of delaminated composite plates are analyzed, and the effects of delamination on the shear properties are studied. A theory developed based on the Rayleigh-Ritz approximation is used. It can deal with the contact problem of delaminated portions with the introduction of constraints on the delamination surface. A significant drop of shear properties is shown. The shear behaviors of delaminated laminates are found to be composed of a complex combination of local delamination buckling and global instability. The buckling and postbuckling behaviors, particularly local deformations, depend strongly on the initial imperfections. The estimation proposed in the present paper is useful to obtain rough estimates of local and total unstable loads.
