A multi-physics Internal State Variable (ISV) theory that couples the thermo-elasto-visco-plastic-damage model of Bammann with electricity-related electromagnetic phenomena was formulated with internally consistent kinematics, thermodynamics, and kinetics. An innovative methodology to experimentally distinguish the ElectroPlastic (EP) effect from the thermal expansion was developed and applied to experimentally validate the proposed theoretical electro-mechanical model. Three series of quasi-static uniaxial tension experiments with titanium, copper, and zinc were conducted and a quadratic dependence of the EP stress drop on the electric current density was observed. This study experimentally confirmed the existence of EP as an electron-dislocation interaction phenomenon. The significance of the non-EP effects in the electromechanical coupling problems was estimated. The experimental procedure limitations were thoroughly discussed as well as the sensitivity and uncertainty, associated with each of the model parameters. Conclusions and suggestions for future work supplement the study. This piloting work on electro-mechanical coupling opened new horizons for modeling and experimental observation of the electroplastic effect.
