Following is a PV design summary as per ASME VIII Div 2 Part 5 "Design By Analysis" and API 6A.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Method: Elastic-Plastic Analysis
Material Model - De-rated True Stress Strain Curve (@ design temp) as per Annex...
Is it possible to obtain the hydrostatic stress [Sigma1+Sigma2+Sigma3)/3]
from ANSYS Workbench for calculating the limiting plastic strain per
ASME VIII Div 2, Section 5.3.3 Equation 5.6
Von Mis stresses for plates & shells can be obtained in Staad.
Is it possible to do so for standard profiles like angles,
hollow sections, beams, etc?
Staad provides combined stresses.
Some codes use Von Mises stresses to specify permissible
stresses.
