Özet
This study aims to investigate the effects of the temperature and strain rate on the yielding and springback behavior of DP1000 advanced high strength steel. For this purpose, material properties were defined using tensile tests at several temperatures (25 °C, 100 °C, 200 °C) and strain rates (0.0083 s -1 , 0.16 s -1 ). Yield loci were estimated by using Barlat-89 yield criteria. Springback behavior is specified by performing V bending tests. No significant effect was observed in the assessment of the effect of temperature on the yield locus and springback. Moreover, it was found that the increase in strain rate increased dramatically the yield locus and springback. © 2018 IOP Publishing Ltd.
