Stress Linearization, Stress Intensity and Tresca*2 results
(OP)
Hey,
I am performing a pressure vessel analysis using ASME boiler code Section VIII Division 2. This requires examining the stress intensity. The stress linearization software provides an average value of the stress intensity Pm + Pb, but the code requires finding the greatest intensity through a section; not an average.
However, the Tresca value is define as a measure of the maximum shear stress. Is the Tresca*2 stress result output a good approxiation of the stress intensity?
Thanks,

I am no expert on the ASME Boiler Code. In fact, I would suggest that you consider posting this on the Mechanical Engineering Forum (forum404) or the FEA forum (forum727), but I would check to see if Strain Energy Density may be a better indication.
