Keywords: buckling, post-buckling, aluminium panels

New aircraft materials permit significant increases in limit stresses. To fully exploit this as weight savings on aircraft, the buckling stability of stiffened panels needs to be improved. Experiments, finite strip- and non-linear finite element analyses were used to investigate panels with sub-stiffening or local tailoring of skin thickness.
