Stress linearization method
Stress linearization method
(OP)
Good day,
I am currently developing a stress analysis for a clamp validation. This clamp will be in a high pipe line installation .While looking in a similar analysis I found that because the stresses were really high in some regions, they used stress linearization on that zone.
But I would like to know a more deep explanation of this method and in what cases does it apply.
Thanks in advance!

RE: Stress linearization method
1. eng-tips, linearisation has been discussed many times, specifically in the "Boiler and Pressure Vessel engineering" forum;
2. Part 5 and Annex 5-A of ASME Section VIII Division 2;
3. WRC 429;
4. Do some examples using both shell and solid elements.
Hope that helps!

RE: Stress linearization method
Can you please tell me why is a bad a idea to employ the linearization of stresses for a V-clamp?
What is the Elastic-Plastic method (using LRFD)?
I am also concern for creep deformation, I was about to compare the linearized stress with the required creep to produce 1% strain.
I really appreciate your time.
