Dear All,
if I only have yield strength, ultimate tensile strength, poisson's ratio, and density data, can I get value for a, b & n for Johnson-cook material?
Thank you for your help
Hi,
For /MAT/LAW2, if user sets Iflag = 1, user will need yield stress ( SIG_y) , Ultimate tensile engineering stress (UTS) and engineering strain ( EPS_UTS ) at necking point. With this new input, RADIOSS automatically calculates the equivalent value for a, b and n.
