Three-dimensional buckling analysis of laminated composite hollow cylinders and cylindrical panels (Q675518)

The buckling problem of thick, cross-ply laminated cylinders and cylindrical panels under combined external loading is investigated on the basis of fully three-dimensional elasticity considerations. The three-dimensional pre-buckling state that is initially employed, assumes zero shear stresses and is suitable for the analysis of both open panels and closed cylinders. This assumption leads to a set of three-dimensional linearized buckling equations. Both sets of three-dimensional prebuckling and buckling equations are then solved using a recursive method.
