Abstract: In thin-walled open-section beams made of fiber-reinforced laminates, symmetric with respect to their midplane, the bending and torsion are coupled. For this type of structural members, a nonlinear finite-element (NLFE) ...

Abstract: In thin-walled open sections made of composite material, symmetric with respect to their midplane, the bending and torsion are coupled. In this paper, new equivalent moduli of elasticity and rigidity are introduced for ...
