Abstract

The biaxial strain-hardening behaviors of aluminum, α-brass, and austenitic stainless steel are characterized in plane and equibiaxial deformation paths using a novel low-cost biaxial device. These tests are complemented by conventional uniaxial tensile tests and by complex strain path studies consisting of uniaxial tension after biaxial pre-strain. The experimental results are analyzed and compared using two criteria of plasticity: von Mises and Hill. It is shown that different stress-strain curves obtained under different strain paths could not be correlated with the phenomenological yield criteria.
