Brief Overview on the Application of Finite Element Method on Flat Rolling Processes

Grain growth in polycrystalline materials stems from the inherent energetic penalty that drives the material to eliminate grain boundary (GB) toward a thermodynamically favored single crystal [1].This concept is illustrated in Figure 1 where the Gibbs free energy, G, of the system as a function of grain size at constant material composition, temperature and pressure is reported. Curve a (black line) represents the classical condition where G
