I'm running a test simulation on a Festo rig, with a hydraulic cylinder measuring 45mm internal diameter and 54mm external diameter. The testing requires an internal pressure of 60Bar with no external pressure applied. The strain gauge and setup I'm running it on I suspect to be faulty, and I can't get any sensible principle stresses and strain answers out of it. Is there any way of working it out by hand? I want to see if it's the gauge that's at fault, the system, or if it just happens to be a strange figure.
Thinking back to my lectures, I recall Lane's equation, but as far as I know you need an external pressure to make that work. Is this the one to use? I haven't done it in ages, so any hints on how to work it out would be useful.
