Abstract

Multi-level modeling adaptive to theoretical treatise of superplastic deformation is proposed not only to make process simulation for superplastic forming but also to describe the microstructural change taking place in materials processing. Use of the unit cell modeling enables us to make theoretical linkage between the macroscopic and the mesoscopic models. The fundamental theory is introduced with some comments on the unit cell model for macro-micro mechanics linkage and the advanced granular modeling for mesoscopic representation of superplasticicty. The sinter-forging process is employed for practical demonstration of the present multi-level modeling.
