How to make flexible material?

I have a part that is made out of a very thin piece of copper foil.  I modeled it simply as an extruded rectangle.  Since the material is so thing you can bend it very easily and fold it back and forth on itself.  In my assembly I want to be able to bend this material upwards.  If it just goes straight out it will hit the mount in front of it while in reality it will very very easily curve up if a force is applied.  Is there a way I can do this?
