Description of experimental setup:
The experimental setup, similar to [1], consists of two punches made of 1.7225 and the aluminum plate positioned between the punches.
The punches are equipped with three thermocouples and one thermocouple at the contact surface between the punch and the workpiece.
A sixth thermocouple is positioned in the center of the workpiece.
The aluminum plate is cooled in liquid nitrogen to  196 °C and the temperature of the punches remains at room temperature.
