Journal of structural engineering (JOSE)Summary: This paper investigates the buckling performance of FRP strengthened aluminium cylindrical airframe shells with initial geometric imperfections. This is studied for the shells with different r/t ratios undergoing different modes of buckling viz. elastic, transitional, and plastic. The difference in buckling response of FRP strengthened and corresponding bare metallic shells with variations in imperfection magnitude are brought out. This study demonstrates that 1) the elastically buckling shells display higher sensitivity to imperfection as compared to plastically buckling shells, and their buckling capacity and axial stiffness increase with FRP.....
