Modelling of Bending a Flat Sheet

I am trying to deform a flat sheet into a semi conical shape. I want to study the stress in the flat sheet as it undergoes deformation into a conical shape ( similar to a piece of paper wrapped around a cone ).
I tried using Solid Mechanics and have created a conical structure ( material : steel ) and rectangular sheet ( material : Al ). The bottom of sheet and cone have been fixed and i am applying a force of 10^9N in Y-direction.
However, I only get a very small displacement of the sheet. Can someone guide me what is going wrong here? My aim is to wrap this sheet around the conical surface.

From just the plot it is very difficult to guess what is wrong. But if you look at the stress color legend, the peak stress is of the order of 10^9 MPa (that is seven order of magnitude larger than the yield stress), so there must be some very fundamental flaw in your model.
