Abstract:The finite element method (FEM) and Monte Carlo method (MC) were coupled to simulate the microstructure evolution of inhomogeneously deformed aluminum sheet after annealing. Finite element method was used to calculate the stored energy distribution of the cold rolling aluminum sheet. On the assumption of the mesoscale non-uniform energy distribution, taking macro-scale non-uniform energy distribution into account, the stored energy distribution obtained from FEM was then used in Monte Carlo method to simulate the microstructure evolution. The modeling results are compared with the theoretical and experimental results and an acceptable agreement is achieved.
Key words: aluminum sheet; Monte Carlo; FEM; recrystallization; stored energy distribution
