Numerical Simulation and Experimental Verification of Joule Effect in Gleeble Thermo-mechanical Simulating Tests

In order to refine the numerical simulation of dynamic tests through considering the Joule effect, a model of thermal-electric coupling for hat-shaped specimen was constructed with Abaqus. Modeling in Abaqus was verified using a simplified rectangular sample by comparison with results from experimental test performed on a Gleeble machine. The heating step of a hat-shaped specimen was simulated for the temperature distribution, which can be used as predefined temperature field of mechanical step. In addition, an extended analysis was specially focused on the use of validation tests on the Gleeble, which allows to predict the phase transition temperature.
