Thanks for your explanation TGS4. I have read Article 5.3 in ASME VIII but I didn´t understand how/why to to apply this code check. Now it makes sense.
However, I still wonder how I can sum three orthogonal principal stresses (S1+S2+S3) when they obviously aren´t pointing in the same direction...
Hi,
I´m working with an elastic analyse of a pressure vessel and according to section 5.3.2 in ASME VIII div 2 2007 the following criterion shall be checked:
S1+S2+S3?4S
What is this criterion and what do I check applying this? Shall I use the absolute values of the primary stresses when...
