Axial Cyclic Hardening Behavior of Metallic Materials under a Constant Shear Stress
The cyclic hardening behavior of metallic materials under a prescribed constant strain rate and constant shear stress is investigated. Both theoretical and experimental studies are found in this investigation. The theoretical development is within the framework of the endochronic theory of viscoplasticity. The constitutive equations of endochronic theory in two dimensions are used. Experiments are performed by the Instron 1322 axial-torsional servohydraulic testing system. Thin-walled specimens made of 1070-0 annealed aluminum alloy are used to be tested. The theoretical results are in good agreement with the experimental data.
