ABSTRACT
A three-dimensional finite element model has been used to simulate the thermal behaviour of the resistance heating system of aluminium alloy specimens tested on a Gleeble thermomechanical simulator. The objective was to adapt the simulator to investigate the rheology of the aluminium alloys in a semi-solid state. The resistance heating system was optimized in order to obtain a uniform distribution of temperature in the tested material. The simulations of heating were carried out using ADINA software.
