Hello all, For Protection Against Local Failure, ASME Sec VIII Div 2 has two methods. The less recommend one is using "Elastic Analysis Method" that I am using. My question is regarding the Weld Joint Efficiency. My design is based on ASME B31.4 so I am using the concept of API 597 for the...

@weldstan , For sure, but what percentage of yield/tensile? for example Div2 specifies 90 of yield. Can we use this practice for Div 1?

Sec VIII Div 1 , states "This Division does not specify an upper limit for hydrostatic test pressure", but if there is visible permanent distortion it can be rejected. My question is in practice how to calculate this limit. Let's say my MAWP is 1000psig. How to calculate upper limit that there...

You can do FEA for buckling using Abacus or Ansys. I have not seen buckling calculation in Nozzle-pro.

Hi Folks, I am performing FEA analysis to investigate a fillet weld. My question is mostly regarding local failure (both elastic and elastic-plastic) as well as fatigue assessment (elastic method) based on ASME SEC VIII-Div 2-Part 5. There is no machining on the weld, so weld toes are "Toe...

Thank you guys.

@r6155: Thanks for the answer. I know how to calculate forming strain using Table 6-1.I am trying to make it zero by heat treatment. The part that I do not know is what should be heat treated to make the forming strain zero. Should the rolled plate itself to be heat treated or weld should be...

Hi Folks, I am using Sec VIII-Div 2-para 5.3.3.1 for protection against local failure. The design is using SA-516-GR70N plate cold rolled to a cylinder. There is a ring welded on OD of this cylinder. Since the load on ring is high, calculation shows to prevent local failure, forming strain...
