Abstract : A new theory for the in-plane elastic behavior of shear-deformable ring-type structures, i.e., curved beams and complete rings, is presented. This theory falls between Bresse-Timoshenko-type ring theory, in which the shear deformation is assumed to be distributed uniformly through the thickness and corrected by a shear correction factor determined in an ad hoc fashion, and two- or three-dimensional elasticity theory. As an example, the theory is applied to the problem of a diametrically loaded thick ring. The predicted normal-stress distribution is in excellent agreement with published results in the literature obtained by photoelastic measurements. (Author)
