| Outline of Final Research Achievements |
In this study, hollow parts having the high compressive force assembled by linearly press hemming for automobiles were developed. The forming limit of conventional hemming on joining ultra-high strength steel parts was investigated. New hemming method for prevention of deformation concentration was developed to improve the limit. The compression test of the hollow parts joined by hemming was carried out. The compressive load was measured, and the fracture mechanism was clarified. New hemming technology for joining ultra-high strength parts for automobiles was successfully developed.
