The research results show as follows. As plastic deformation increases, the Young's modulus of material continuously changes. This variation law is able to be described using a piecewise linear function .Hardening model and whether the variation is considered or not make great effet on springback prediction. It is proved that the springback prediction result which adopts the elastic-plastic constitutive model based on INLK hardening model and the variation of Young's modulus is considered, is more close to experimental result. After the sheet metal undergoes multiple bending, the corner radius and bending height also affect springback greatly.But the effect trend is different. At the same time, the reliability of springback research using numerical simulation is proved.

The purpose of this research is to examine the relation between ruminative thought and mood fluctuation. Similar to the Nolen-Hoeksema's progressive paradigm, we divided the experimental period into three parts, including average days, severely and long-term negative mood days, and negative mood episode. Combined with the Fritz's viewpoint of multidimensional rumination ─ instrumental rumination, emotional-focused rumination, and meaning-searching rumination, this research attempted to clarify the role of rumination in the process of emotional recovery.
