Buckling and PostbiiekSing Studies on Stiffened Composite Panels with Circular Cutouts Author : Byji Varughese, A. Kishore 0 , K. Radhakrishna and M. Subba Rao

WHAT IS THIS DOCUMENT ABOUT? : An analytical study has been carried out to investigate the buckling behaviour of rectangular composite stiffenedpanels with circular cutouts. The effect ofparameters such as cutout size, inclination ofcutoutflange, location ofstringer 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 thepreliminary design stage ofcomposite wingpanels.
