OPTIMIZATION OF JOHNSON-COOK PARAMETERS IN FINITE ELEMENT SIMULATION OF HIGH-SPEED CUTTING TI-6AL-4 V ALLOY

OPTIMIZATION OF JOHNSON-COOK PARAMETERS IN FINITE ELEMENT SIMULATION OF HIGH-SPEED CUTTING TI-6AL-4 V ALLOY

In order to obtain the Johnson-Cook（J-C） constitutive parameters that can exactly reflect the plastic flow behavior of the workpiece material under the coupling effect of high temperature, high strain rate and large deformation occurred in high-speed cutting, and make it to suitable for the high-spe...
