Buckling of Delaminated Long Panels Under Pressure and of Radially-Loaded Stiffened Annular Plates.

Abstract

The buckling of delaminated, long, thin, cylindrical shells and panels is investigated. The thin panels are pressure-loaded and their geometry is quasi-isotropic. The effects of boundary conditions, delamination size, and delamination position on the buckling load are studied. Moreover, the buckling analysis of multi-annular, laminated plates is presented. The annular sections are made of different materials, their size is varied, and the composite circular plates are supported in various ways. Stiffened plates, full or annular, are also analyzed. Keywords: Laminated shells; Delamination Buckling; Damage Tolerance; Annular Plates; Plates with Holes; Laminated Circular Plates.
