Explicit Coupled Thermo-Mechanical Finite Element of 5182 H111 Aluminum Alloy

The paper presents a method to estimate workpiece-die heat transfer coefficient is presented using FEM simulations.Simulation using finite element method shows the die heating along time for various heat transfer coefficients.However, the formation of the defect could be successfully suppressed by changing the frictional Conditions of the workpiece/dies interface.The aim of the research is to reach consistent value for heat transfer coefficient between workpiece-die; to later study ways to minimize it, decreasing thus the thermal gradient in the dies and, as a consequence, minimizing the fatigue effect for each tree blows only two parts are produced.
