According to ASME Section VIII Division 2 paragraph 5.2.4.4, and as part of the assessment procedure, an elastic plastic material model shall be used in the analysis:
"An elastic plastic material model shall be used in the analysis. The von Mises yield function and associated flow rule should be utilized if plasticity is anticipated. A material model that includes hardening or softening, or an elastic perfectly plastic model may be utilized. A true stress–strain curve model that includes temperature dependent hardening behavior is provided in Annex 3-D. When using this material model, the hardening behavior shall be included up to the true ultimate stress and perfect plasticity behavior (i.e., the slope of the stress–strain curves is zero) beyond this limit. The effects of non-linear geometry shall be considered in the analysis"
I made an elastic plastic material model, by using Annex 3-D and that website:
(this example were made with ANSYS)
My questions are:
1. When I enter the material properties in Solidworks I have a lot of options there, which one should I used in order to meet the ASME rules for non-linear analysis?
2. Anouther question regarding the stress-strain curve, does the strain in the curve is the total strain or the plastic strain.
3. Is it possible to meet the requirements of ASME VIII-2 with solidworks non-linear?
