Abstract
A three-dimensional (3D) explicit finite difference model has been developed to simulate the thermal behaviour of specimens subjected to controlled thermal cycling patterns using direct resistance heating in a Gleeble thermomechanical simulator. Model predictions have been compared with temperature measurements performed on 2024 aluminium alloy, 0.2% plain carbon steel and 316 austenitic stainless steel specimens in the simulator. The specimen materials were chosen to provide widely differing thermophysical properties and, in the case of the steels, to allow a comparison of the predictions with and without an to phase transition.
