Ernst Florens Friedrich Chladni was a German physicist and musician. His most important work included research on vibrating plates inventing a technique to show the various modes of vibration on a rigid surface, known as Chladni figures or Chladni patterns due to the various shapes or patterns created by various modes.

This simple simulation shows that the Chladni patterns are really captured by the modal analysis performed by FEA. It is very interesting to see the FEA modal figures on the plate are exactly the same to those discovered by Chladni in 1800.
You can see on the showed figure, a comparison between the FEA patterns (on the left) and the corresponding Chladni patterns (on the right).
