Chladni Plate
Application ID: 67591
A Chladni plate is a metal plate that is covered in sand and subjected to vibrations. At certain frequencies, the vibrations produce standing waves, resulting in sand patterns formed on the plate. The vibrations are either formed from a violin bow at the side of the plate or a wave generator at the center of the plate.
This application uses the Plate interface to calculate the resonant frequencies of a certain shape. The eigenfrequencies represent standing waves formed within a certain frequency range. When running the app, the user can choose from four shapes:
- Square
- Triangle
- Circle
- Violin body
The plate thickness, material, and frequency range are also editable. After running the app, you can look at the various patterns from a top view or a lateral view, which shows standing waves that form in the plate.

This application example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
