Plate with enforced displacement

Hello everybody,
I'm trying to simulate a film of Mylar material (0.127mm of thickness), fixed in 6 holes and subjected to an enforced displacement of 0.786 mm, normal to membrane's plane. The purpose is to observe deformation and calculate force on the nodes which the constraint is applied.
Referring to an online pdf, I set both SPC and SPCD with the same dof and the same value of constraints on the nodes which the displacement is applied.
Hovewer, when I visualize the result, the membrane moves only in the Z direction, bending on X. If I check displacement in X and Y, I find 0... In reality, I expect to find a little displacement in Y direction, not only in Z.
I suppose that this depends on property setted for model "PSHELL". Can anyone helps me? Thanks!

I share my model, gime me your opinion please.
