If there are no axial constraints, then the axial strain in the two cylinders and the epoxy are the same and the axial force is zero...

you can not analyze cylindricity with only a size measurement. you must know the form error of both diameters otherwise it is a waste...

Roundness is 50micron. If the parts are assembled with no force required, and have similar thermal expansion coefficient, then the...

If its meant to bond them the stress is induced in the ceramic. Allow the steel to freely expand. The ceramic is a good insulator, its...

Yes, except for the turn on transient, when the system is not in equilibrium. The steel will be hot, the ceramic cold. That may be the...
