Stress Linearisation Question
Stress Linearisation Question
(OP)
Hello, I'm a recent Mechanical Engineering graduate and have recently began working with Abaqus. I am designing a pressure vessel (obviously in a junior role, trying to get to grips with the software etc). Now I am getting my head around the idea of stress linearisation (wasnt mentioned at uni) and splitting the stress into a membrane and a membrane + bending component. What I am not too sure about is the output generated by Abaqus (textfile). What is the difference between the "Component Results" and the "Invariant Results"? I have been advised to use the invariant results but wasnt given much of an explanation, and I could not find anything in the help file. Thanks for any help provided.

A word of advice - your focus at this point in time should be the Code (ASME, PED, etc), and less about your FEA software.
