Membrane under Pre-Tension

Question asked by Freddie Santiago on Jan 28, 2013
Latest reply on Feb 3, 2013 by Freddie Santiago

I am a student and begginer with Solidwork, working on a model of a membrane deformation due to an apply pressure. Similar to a musical drum membrane. Following a trampoline tutorial in nonlinear manual I was able to model my experiment using Static(Linear) as well a nonlinear simulation. The model works fine except my results are off(displacement due to applied pressure) since I don't know how to model the membrane pre-tension. I basically want to model the pre-tension of the membrane, like a drum and then apply my pressure to deform the membrane. How I can model that Pre-tension?

Will appreciate any help....
