Abstract

Theoretical definitions of the multiaxial plastic flow surface are exact; however, ambiguities arise in the experimental measurement. A new method for measuring the multiaxial flow surface based on maximum elastic stress rate is proposed which eliminates these ambiguities. It is applied to biaxial yielding.

Keywords:
flow stress, stresses, measurement, flow surface, multiaxial stresses, plasticity, proportional limit
