| Outline of Final Research Achievements |
The purpose of the present study was to understand the deformation characteristics, including work-hardening behavior, of electric resistance welded steel tubes and to develop procedures to evaluate and to predict the characteristics. As a result of the study, the effect of the deformation history during manufacturing processes of tubes on the deformation behavior of tubes was revealed in detail. Experimental and numerical procedures to evaluate easily the deformation characteristics were also proposed. Moreover, in order to improve the formability of the tubes, the effect of the deformation characteristics of tubes on the formability was also discussed.
