Does anybody know how to calculate a comprresive stress from a out-of-plane
deformation
value of free-standing membrane? Or could you tell me related paper or reports?
I have a free-standing Si square membrane that were from SOI substrate. The
membrane is
fabricated in the center of SOI substrate. I mean every edge of the membrane is
supported by the
SOI substrate. The membrane has a thickness of 3um, a lengh and width of 1mm and
a
out-of-plane deformation of 2um.
I want to know how much compresssive stress is loading to the Si membrane.

Thank you.
