Greg,
Of course it isn't. Just trying to make things as easy as possible when comparing measured results to test results. It's advantageous to do so when you're placing 150 strain gages.

rb1957,
Thanks for the tip. I think using 4 uniaxial gages (one on each tube face) is the best way to go, though I'll have to settle for 2 (on adjacent, perpendicular faces) in many cases because only 2 faces are exposed.
I disagree with your 2-noded rod statement. FEA is giving me...
Thank you for your comments everyone (I was without internet yesterday). After reviewing them and doing a little investigation, I have learned the following:
1. The best place to locate a strain gage on a beam is at an existing node (versus at mid-element) because all the information I need is...
My company is gearing-up to conduct a structural test on a railcar and I have been charged with locating strain gages for the test. The gage info will be used to determine if yielding occurs and to validate the FEA model. The model is large and complex, made up of beam, plate and solid...
