Stress at bolt hole location
Stress at bolt hole location
(OP)
Hi all,
Am doing FE analysis of plate heat exchanger.
The FE results are showing high result at the bolt holes location, which is local stress, but that is still higher than the allowable stresss(1.5Sm).
Can I avoid the stress at that location.
If so what is the exact reason to avoid the stress at bolt hole locations.
Please help

HOW have you determined that the allowable is 1.5Sm?
HOW are you interpreting the FE results?
You need to provide significant more details to get a useful answer.

The stress which is observed at bolt hole location is clearly local stress.
To interpret the stress at the bolt hole locations, i dont have any exact calculation right now.
if you suggest something regarding this, it will verymuch helpful for me.
thanks

What edition of Division 2 are you using? What FEA software? Do you know what it means to linearize stresses? Have you read (and understood) WRC-429? Please search the archives here for numerous discussions on stress linearization and stress classification.
In my opinion, you are in over your head, and need some mentorship by an engineer who has significant experience applying finite element analysis results to pressure vessels.
