| Outline of Final Research Achievements |
Ultra-lightweight construction is advantageous to promote the effective use of energy, when it is applied to vehicles et al. Elastic recovery and large amount of springback, which is induced by the residual stress of stamped high specific strength material used in ultra-lightweight construction, makes the forming into the desired shape. In this research, forming in the warm temperature range to suppress spring back and joining of dissimilar thin sheets were investigated, taking metallic sheets and non-metallic sheets as target materials.
