    Abstract

    An analytical study has been carried out to investigate the buckling behaviour of rectangular composite stiffened panels with circular cutouts. The effect of parameters such as cutout size, inclination of cutout flange, location of stringer with respect to the cutout and stringer height on the buckling and postbuckling performance has been studied through non-linear FE analysis. The study has helped to develop a few guidelines in the preliminary design stage of composite wing panels.
