Abstract

Recent research has shown that passing DC electric current through a metallic tensile test specimen during deformation decreases the energy required to deform a specimen to a greater extent than that expected due to resistive heating. Prior resistive heating models have been successful in predicting temperatures in the absence of test sample deformation. In this work a 1D transient thermal model of a cylindrical cross section tensile bar is solved for the case where the sample is carrying a large DC electric current while simultaneously being deformed to fracture. The model uses a simplified representation of the necking process to provide geometrical information to the heat transfer model during the latter phases of deformation. Simulation results are compared to experimental surface temperature data.
