Ductile damage modeling at elevated temperature applied to the cross wedge rolling of AA6082-T6 bars
چکیده انگلیسی
In the paper, a modification of the Oyane-Sato fracture criterion providing the dependency on temperature and strain rate is proposed and applied to a cross wedge rolling process carried out on AA6082-T6 bars at elevated temperature. The modified fracture criterion was calibrated by means of hot tensile tests conducted at varying temperature and strain rate spanning the hot temperature range for the given alloy. Changes in the material formability were identified as a function of the testing parameters and also linked to the material microstructural characteristics. The fracture criterion was then implemented into the calibrated finite element model of the industrial process and validated by comparing the numerical and experimental outcomes.
