In exercise RD-T: 3500 Tensile Test Setup, how can the output plots be created...

Hello.

I want to complete the exercise RD-T: 3500 related to RADIOSS. I cannot generate the Engineering_Stress plot in W2 and the Engineering_Strain in W3. These two plots are used to generate the plot in W4. For the Engineering_Stress and the Engineering_Strain I am using the h3d file of the run -for the others I am using the tensile_start_edgT01 file-, but the shape is different from the ones shown in the exercise.

Could you help me please to complete these three plots -Engineering_Stress, Engineering_Strain and Stress-Strain plots?

Thanks

Edgar Fernando

    You need to calculate the engineering stress from the T01 (Force / original cross sectional area), not take it from the h3d, the stress in the h3d is true stress, I attached an annotated mvw with all the steps in it
