The identification of improved Johnson-Cook constitutive model in a wide range of temperature and its application in predicting FLCs of Al–Mg–Li sheet
For the Al–Mg–Li alloy sheet, a series of uniaxial tensile tests are firstly carried out under different temperatures (25–450 °C) and strain rates (0.00025–0.01 s−1). Then, to describe the flow behavior of the sheet, the improved Johnson-Cook constitutive model (hereinafter abbreviated as ‘improved...
