Vibration in a thin disk

I am trying to simulate the displacement in a thin (1mm thick), circular (182mm diameter) disk caused by a sinusoidal input at the center of the disk (essentially, simulating the displacement that occurs when you shake a Chladni plate).
Please excuse me if this topic has been covered elsewhere. I have searched quite a bit and have not been able to simulate what I am trying to do. It is also possible I do not understand enough about vibration to correctly interpret what I have found.
The main trouble I am having is: how do I prescribe a sine wave input at 500 Hz acting on a 10cm diameter circular area centered on the underside of a larger thin disk? What physics and studies should I be using to simulate this condition?
Thanks,
Sam
