Hi team, I was trying to run a simulation with Non linear material data. I have the Stress Strain curve details for steel as below:
0 0
0.0005 100
0.001 200
0.0014 210
0.002 220
0.005 260
0.01 280
0.05 350
0.1 380
0.15 400
0.2 405
I have been traditionally using MATS1 card, where we use Plastic Strain vs True stress, However I wanted to use the full Non Linear curve (True Stress - Strain). When I am using that through TYPSTRN=0, I am getting the following error
"The plastic material data specified on the TABLES1 bulk data entry ID=1
is invalid. The slope after the initial yield point is not less than the
Young's modulus. ( 2.000000e+05 >= 2.000000e+05 ) at the segment 2."
What mistake am I making, and How to rectify it. I am attaching the .fem file here for reference.
