Hello, I was wondering if someone can tell me the difference between the definitions for user defined results:
Is SMAXSHEAR essentially the resultant vector of SX, SY and SZ, or is CONTSFRI?
I've tried looking at ansys student documentation / searching on google but can't find anything. I want to be able to compare shear stresses with shear strains and normal stress (i.e., pressure) with normal strain, but I'm not sure which user-defined result to use.
I'd really appreciate any help with this.

For SMAXSHEAR please see the following online resource: e-news-stress-calcs-002.pdf (infinite.nl)
For CONTSFRI - where did you find this expression?

Thank you for the link, that's very helpful.
In terms of CONTSFRI, i've attached a screenshot of the option available in the worksheet:
Based on the link you sent me, I assume for my application using contsfri (frictional stress) is the best option since I want to look at the shear along a surface, then compare those shear stresses and pressure when applying different boundary conditions/ materials. Is my understanding correct?
Sorry if these are silly questions, there's just so many options it's hard to know which is most appropriate without having full descriptions.
Thank you so much for your help!

The expression CONTSFRI is for contact friction stress. Please see if the following link helps you: Maximum Shear Stress Result In ANSYS® Structural Analyses (mechanicalland.com)

Sorry I should have previously clarified - I'm dealing with an assembly and am interested in the contact pressure/ resultant shear on the contact body.
Thanks for your help.
