Improved Johnson-Cook constitutive model (Improved J-C model)Modified M-K modelForming limit curves (FLCs)Al–Mg–Li alloy sheetFor 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–...
The influence of the choice of a set of parameters for the Johnson-Cook constitutive model on the results of an orthogonal cutting model has been studied extensively with twenty different sets of parameters for Ti6Al4V. It results of this study that: Acknowledgements Computational resources have be...
tem perature and strain ra te, the deform ation degree of a-A l firstly increases and then decreases. A segm ented model that can accurately describ e the high tem perature flow behavior of A356 alum inum alloy was established using the m odified Johnson-Cook constitutive model and...
