Abstract

The purpose of this paper is to extend the applicability of the complete differential elasto-plastic constitutive equations of the endochronic theory todescribe the material ratchetting of a beam under a steady axial load and cyclicbending. Based on the assumption of the linear distribution of the throughthickness strain of a beam under cyclic bending, the stress-strain behaviorof each through-thickness point can be found theoretically. Experimentaldata of a lead alloy under a steady axial load and cyclic bending from Hydeet al. are used for comparison with theoretical predictions. It is shownthat the theoretical results are in agreement with the experimental data.
