A numerical study on nonlinear bending performance of transversely loaded composite singly curved stiffened surfaces

The review of recent literature shows that the bending performances of transversely loaded laminated composite singly curved stiffened surfaces are not studied in detail using the geometrically nonlinear strains. The present paper aims to fill that void and proposes an isoparametric C° finite element formulation combining von-Karman nonlinearity and Sanders’ first approximation theory. The curved surfaces are simulated using nonlinear strains....
