Webb6 apr. 2024 · Our investigations show that both deformation and stress response of an elastic torus are sensitive to the radius ratio. The analysis of a torus must be done by using the bending theory of a shell instead of membrane theory of shells, and also reveal that the inner torus is stronger than outer torus due to their Gaussian curvature. Webb1 apr. 1995 · The bending of sheets is a widely used metal-forming process. When analyzing the various sheet-bending processes, there is a need for an appropriate model to describe the bending couple-curvature relationship over the whole range of bending radii (from infinite curves to sharp bends).

"WebbThe beams are subjected to pure bending at the central section, by adding weight on the weight hanger, and the bending moment is kept constant and shear force is zero too. The maximum deflection at the mid span of the beam will be measured. The elastic modulus of the beams’ material will be determined from the flexure formula. " - Theory of pure bending
