Hello,
Is there a guiline in terms of percentage of plastic strain to get in a pressure vessel during a pre-straining test in order to limit the plastic deformation during pressure test or operation?
Is there something about pre-straining in the ASME? If so, what reference?
Thank you.

Hello,
In some cases, for a HEXA20 3D-model, a peak of stress can be obtained (max VM stress at one node only).
In order to get the right interpretation and to compare the max stress to a criterion, different methods can be used as seen on different forum:
- 1st method: the peak is not taken...
Hello SteveyB,
Here are the values in MPa of the two coefficients for a Mooney-Rivlin law for elastomers (EPDM).
C1(or C01)= 0.7 and C2 (or C10)= 0.2 for a 70 Shore A.
Any idea about my question, subject: Hex vs Tets / Different stress level?

Hello,
I am dealing with a mechanical model in linear analysis.
The model represents a cylinder made of steel with a top and a bottom flange. The bottom flange is fixed and I apply loads on the top flange. By the way, the cylinder has a hole at mid-height.
Comparing the...
