摘要

•R-value of 7B04 was obtained at 200 °C by an electrical heating device with DIC system.•Strain and displacement fields of Pottier test were obtained with DIC system at 200 °C.•Parameters of Yld2000-2D were determined by the FEUM-U-F method with Pottier test.•Deep drawing test was conducted to validate the determined yield function accuracy.
