Hi,

I'm looking into the subject of "Chladni plates":

http://www.physics.montana.edu/demonstrations/video/3_oscillationandwaves/demos/chladniplates.html [Broken]

For a lecture I'm supposed to prepare, and I'm looking for information on how exactly a two-dimensional surface vibrates under forced oscillations. It's no secret that the motion of a 1D string is governed by the simple wave equation. So which equation governs, for example, a thin square plate?

Thanks,

Chen
