  Hi all. I need your help. I can't seem to find the Johnson-Cook parameters for the two materials.
  Steel 46Cr at 650 yield strength
  AISI 630 steel at 750 yield strength
  Help please, maybe someone already has this data?

  i guess you havent done your literature review yet, i would encourage you to do it before you start your numerical work, infact, it is recommeded to perform your own trail of experiemnts using SPHB test if you can else those numbers are hard to getby without an through study .
  Cheers, Ram

  Hello javat33489,
  As Ram suggested you need to have experimental data to determine this.
  Additional links for your study purpose: Will not give you direct parameters which you are expecting but you can use this for your better understanding,
