Outline of Final Research Achievements

In this study, improvement and optimization of formability of FCC sheet metals was analyzed by multiscale finite element method based on misorientation theory. Bendability of an aluminum alloy A6022 and Cupper alloys Cu-2.30Ni-0.65Si, Cu-8.0Sn-P was optimized by asymmetric rolling parameter and annealing time. The crystal texture was obtained for high-bendability and low-springback sheet metal by the optimized process parameters.
