Thermo-Mechanical Simulation Model Development on Residual Stresses in Rolled Aluminium Alloy (Retracted)

Purnendu Mondal* and Christophe Pinna

The goal of this project is to investigate the Residual Stress in hot rolled aluminium alloys where both experiments and computer simulation will be implemented in order to get highest degree of investigation. This project is a miniature investigation process of real problem faced by AIRBUS, in the field of failure of wings against superfluous residual stresses. The residual stress level achieved from simulation matches to what received from the hole-drilling measurement after quenching process, hence, the necessity of the complex and expensive hole-drilling method can simply be omitted in the real industry resulting huge time saving in mass production units.
