Wow thank you for the quick and great responses. I'm happy I can solve this by hand now, next is wrapping my head around it all. I'll do some more reading and practice problems.
Thanks again guys.
How do normal stresses arise in a "pure" torsion problem?
Example problem is 12" long solid shaft of 1" OD. One end is fixed, the other has a moment on the face of 500 lbin. Part was discretized in 3D using 2nd order trias. The resulting shear stresses match up fine with the simple hand...
