- W2364630264 abstract "High strength steel stamping forming has generally springback defects. The DP780 sheet bending and springback were studied by three-point bending test and updated Lagrangian method of Marc.MSC software. The effects of indenter reduction on springback angle, stress and strain distribution were analyzed. The deformed microstructure morphology and flow were observed. The results show that: DP780 steel springback angles increase with the increase of indenter reduction; banded structure in arc zone is more obvious than in straight zone, and metal flow, stress and strain are mainly concentrated in the vicinity of the arc zone. Stress and strain on both sides of the neutral layer are substantially symmetrical.The simulation results agree with the experimental results, and the average error is 9.4%. It is able to get a more accurate springback during sheet metal bending, which has a certain reference value to the study of DP steel sheet bending." @default.
