Recently CAE(computer aided engineering) has been spread widely in metal forming. Large model calculation and remeshing in heavy deformation by FE analysis become possible because of the improvements of hardware and software. However the obtained outputs in FE analysis are limited in shape, temperature, various stress and strain. So it is difficult to design optimal process to obtain a final target properties in quantitatively by the current FE analysis system. We have developed digital engineering system DAINUS(DAIdo NUmerical process engineering System) consists of 4 prediction module (1)DAINUS-damage, (2)DAINUS-grain, (3)DAINUS-life, (4)DAINUS-cavity. DAINUS is installed in commercial FE analysis code using user subroutine, and can predict a ductile fracture by DAINUS-damage, micro-structure and mechanical properties by DAINUS-grain, die life by DAINUS-life, cavity consolidation by DAINUS-cavity. Nearly all kind of information in metal forming can be obtained in concretely and in quantitatively by DAINUS. In this paper, the features and abilities are introduced.
