      Hi!

      I'm new to Ansys, and i'm in the process of defining a new material in Workbench (Engineering Data)

      When defining a new metal, should i base all input on true stress/strain? or use engineering stress/strain?

      Should the "Tensile Yield Strength" be based on the 0.2% offset? 

      Thank you!

      Regards
      Siggi

      Hi Sigurd, You should use plastic strain versus true stress to define the hardening (stress-strain) curve of your metal. Initial yield stress (0.2% rule) and ultimate tensile strength are commonly defined based on engineering stress.
