Abstract
Thin-skinned fibre reinforced composites exhibit poor behaviors in compression and bending. Wrecking the excellent performances proved in tension and in plane shear. In order to counterbalance this quite natural tendency present at all thin shells, there are two ways of action: creating stiffened panels or sandwich materials The paper presents, in the frame of the first structural option, some results obtained for stiffened composite panels loaded with lateral pressure and some considerations based on a study concerning the buckling and post buckling behaviors of similar panels subjected to axial compression.
