The field equations governing primary and secondary creep, with the inclusion of elastic strains, in the Saint-Venant theory of pure bending are reduced to a single equation in the tensile stress. It is shown how, from this equation, the limiting or steady-state stresses can be obtained. This equation is then used to derive inequalities which describe the shape of the stress profile at all times, and from which bounds on stresses and displacements are easily obtained. The inequalities, which are similar to those of[1], are established using new arguments which greatly simplify the analysis for the case of primary creep. |
