Hello,
Does anyone know if Abaqus is able to calibrate/fit Johnson cook material parameters (A B n m & D1-D5) from uniaxial stress-strain curves at different strain rates.
I have these uniaxial stress-strain curves at different strain rates but i dont know how to generate the johnson cook parameters. Also i want to know how Johnson Cook is handeling different E-modules at different strain rates. I`m working with fiber reinforced thermoplastic which has different stiffness at different strain rate.
Appreciate you urgent help!
Best regards
