Outline of Final Research Achievements |
The purposes of the present study were to develop crystal-plasticity models for prediction of deformation behavior of metallic sheets that are expected to be used for structural components and to apply the developed models to press forming simulations. We proposed new models that could predict deformation behaviors of various metallic materials, such as steels, magnesium alloys, and commercially pure titanium, under different loading paths accurately. The underlying deformation mechanisms were also revealed on the basis of crystalline microscopic deformation behavior using the proposed models. Moreover, we also examined a framework to utilize the proposed models for determining material parameters used in sheet metal forming processes.
