Is it a diaphragm or a cantilever?
If its a cantilever where did you apply the force with respect to the
supported end?

In either case you claim to have deflected the 3mm object 40 mm! Think about
it, you cannot deflect a pinned object (whether diaphragm or cantilever) a
distance in excess of its given dimensions unless its elastic. Is this a
rubber diaphragm?
