Advanced fiber-reinforced composite materials such as graphite-epoxy have Research on the buckling and postbuckling behavior of stiffened panels has been of interest of flat and curved stiffened graphite-epoxy panels loaded in compression. They also conducted experimental comparison between specimens with Compression tests have been experimentally performed on composite Two different resins, epoxy and vinylester, were considered to residual tensile and buckling behavior of composite structures. Under mode II loading, three-point end notched flexure specimens were graphite/epoxy composites.
