Morcuse, thanks for your comment. I am not familiar with ASME VIII/D1. I see it is important to point here which division we speak about here.
From the book:
"ASME Code, Section VIII, Division 1 does not explicitly
consider the effects of combined stress. Neither does it give
detailed methods on...
EdStainless, I have different point of view. We have to extract equivalent stress in our assessment. To be compared with allowable stress. We can’t take just maximum stress from any point. First of all we have to obtain the principal stresses i.e. when all stresses are without shear stress. In...
There are three stresses in perpendicular directions (hoop, radial and longitude). In case of use maximum shear stress theory we should to take in to account maximum difference between two of these. In case of all positive stresses are the minimum stress it is pressure in radial direction and we...
Look in DEP 31.22.00.31 for some allowable data for nozzle. Although API610 for pumps nozzles. But all of these are common practices of certain company.
Generally this values are really low in due to no one made detailed analysis of these nozzles. And there are some difference for which device...
Hello,
I'm going to do fatigue assessment according to EN 13445-3 part 18. For this reason am building FEA mesh now and I have some doubts. There are two methods how to extrapolate stress from nodes which used for stress extraction to the weld toe point. First method is by two nodes with...
