Modelling of a PZT Piezoelectric Patch in Ansys WorkBench
Therefore, in order for me to get lighter matrices, I decided to use the element type solid5, which is supposed to have only a linear element order for the mesh. Piezoelectric Analysis and Example: For sample analyses, see Example: The program converts a piezoelectric strain matrix [d] matrix to a piezoelectric stress matrix [e] using the elastic matrix at the first defined temperature.
I see only one element in your image. I don’t know what you mean by getting no results as there are so many ways a solve can fail. Any ideas of why this could happen? For modal analysis, Block Lanczos is the recommended solver. Permittivity Matrix Dielectric Constants. Once modelled everything, I used a APDL command to give some piezoproperties to the body which represents the piezo patch.
Mode-superposition transient and harmonic analyses are available. The assembled matrix typically becomes ill-conditioned when the magnitudes of the structural DOF and electrical DOF start to vary significantly more than 1e See the Command Reference for more information on the MP command.
The sparse solver is the default for static and full transient analyses. Thank you very much for your help.
IEEE terms [c 61c 62c 63c 66 ] would be input as the xy row. If the piezoelectric effect is not desired in these elements, simply define very small piezoelectric coefficients on TB. IEEE constants [e 41e 42e 43 ] would be input as the yz row.
The analysis may be static, modal, harmonic, transient, or prestressed modal, harmonic, or transient. Home Leaderboard Activity Badges. Recent Activity ssb41 is a new member in the forum.

Some important points to remember are:. Piezoelectric Analysis with Coriolis Effect.
You can define the piezoelectric matrix piezkelectric [e] form piezoelectric stress matrix or in [d] form piezoelectric strain matrix. Dear Paolo, When bending solid elements, it is required to have two or more elements through the thickness. The [e] matrix is typically associated with the input of the anisotropic elasticity in the form of the stiffness matrix [c], while the [d] matrix is associated with the tutorizl matrix [s].
The Supernode and Subspace solvers are also allowed. The superscript “S” indicates that the constants are evaluated at constant strain. See the Command Reference for more information on these commands. Piezoelectrics is the coupling of structural and electric fields, which is a natural property of materials such as quartz and ceramics.
IEEE constants [e 61e 62e 63 ] would be input as the xy row. Applying a voltage to a piezoelectric material creates a displacement, and vibrating a piezoelectric material generates a voltage.
