Abstract
Present research involving Electrically-Assisted Manufacturing (EAM) has shown the advantageous effects that an applied current flux provides on the mechanical properties with respect to part formation. Overall general results using this process include the reduction of the flow stress during forming, increased achievable deformation, and a decrease or elimination of springback. Specifically targeting the compression process, this paper evaluates the stress-strain relationship and develops from experimental results an initial stress predictor function that includes the effect of electrical current. Once developed, the derived empirical model is shown capable of estimating the flow stress for an EAM upsetting test at various current densities.
