Buckling of Delaminated Shells and Multi-Annular Plates.

Abstract

Buckling of delaminated thin cylindrical shells is investigated. The thin cylinders are axially-loaded and their geometry is virtually isotropic. The effects of boundary conditions, delamination size, and delamination position on the buckling load are studied. Buckling analysis of multi-annular plastes is also presented. The annular sections are made of different materials, their size is varied, and the composite circular plates are supported in various ways. The rigidities of the various parts are varied in order to cover the cases of plates with holes, with rigid inclusion, and ring stiffeners. Keywords: Laminated shells; Delamination buckling; Damage tolerance; Annular plates; Plates with holes.
