Viscoelastic Pure Bending Layered and Composite Prismatic Beams

Abstract

The article carried a generalization of the technical theory of pure bending uniform prismatic beam of constant thickness and height in case of viscoelastic laminated composite beam. Used hereditary theory of viscoelastic creep uniformly aging bodies. Calculated averaged by Voigt and Reuss values of deformation parameters of the composite beam in pure bending.The effective instantaneous elastic modulus and instantaneous radius of curvature of the neutral layer of a flexible beam. Discovered that the Hill’s effective values of instantaneous elastic modulus for bending of a beam and for uniaxial tension / compression viscoelastic composite rods are the same.
