Stress Linearization as per ASME Sec VIII Div 2 Part 5 and Paraview Help 1

[az5333]

Hello. I am trying to perform Stress Linearization as per ASME Sec VIII Div 2 Part 5 rules for Plastic Collapse failure check for the first time and I was looking forward to some guidance. I have gone through the past discussions on the subject and the formulas to perform the stress linearization. I am using SimScale software for the FEA Analysis. I extracted the .pvd file and now I am post processing results in Paraview by creating a Line and viewing the nodal values of the stresses across that line. I have the following question:

- As I understand (please correct me if I am wrong), we need to calculate membrane and bending stress components for each of the 6 stress tensor components. For this, I would want a raw value of the stress component at each node (for example σxx, σyy and so on). I wanted to ask what order shoudl they be in Paraview and how can I transform them to local coordinate system tangential, hoop and meridonial?

Appreciate some detailed insight and help in this regards. Thanks.

Cauchy stresses are also available in SimScale output.

Engineers, think what we have done to the environment !

Hi goutam_freelance,

Thanks! Just found it. Do you know how these are ordered when I view the results in Paraview? I mean first 3 are probably x,y and z, but then after that what is their order?

See the post process screen from SimScale output for Cauchy stress options.
