Radially Polarized Piezoelectric Transducer
Application ID: 6147
This tutorial model shows how a user-defined coordinate system can be used to create any type of directional polarization of a piezoelectric material. Results are shown for the case of radial polarization of a piezoelectric disk. The piezoelectric material is PZT-5H. The example shows a static analysis. Visualization of the cylindrical coordinate system as well as the stress/strain in that system are shown.
This model is included as an example in the following products:Acoustics Module MEMS Module Structural Mechanics Module
however additional products may be needed to reproduce it. This example may be created and run using components from the following product combinations:
- COMSOL Multiphysics® and
- CAD Import Module and
- either the Acoustics Module, MEMS Module, or Structural Mechanics Module
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 Specification Chart and make use of a free evaluation license.
