As explained for the piezoelectric matrix, most published piezoelectric materials use a different order for the [c] matrix. This section follows the IEEE standard notation for the elastic coefficient matrix [c].
Piezoelectric Analysis and Example: A typical application tuorial piezoelectric analysis is a pressure transducer. Home Leaderboard Activity Badges.
If you are concerned with having a very small model for a later stage transient dynamics? Permittivity Matrix Dielectric Constants. The Supernode and Subspace solvers are also allowed. IEEE constants [e 51e 52e 53 ] would be input as the xz row. Material Properties for Piezoelectric Analysis. If the piezoelectric effect is not desired in these elements, simply define very small piezoelectric coefficients on TB.
Hints and Recommendations for Piezoelectric Analysis. Depending on the chosen system of units or material property values, the assembled matrix may become ill-conditioned. See the Command Reference for more information on these commands.

I see only one element in your image.
The system is the one shown in the following picture, where there is a PZT layer applied to a Structural Steel beam: The superscript “S” indicates that the constants are evaluated at constant strain.
The program converts a piezoelectric strain matrix [d] matrix to a piezoelectric stress matrix [e] using the elastic matrix at the first defined temperature.
For a sample analyses, see Example: I don’t know what you mean by getting no results as there are so many ways a solve can fail. IEEE constants [e 41e 42e 43 ] would be input as the yz row.
To specify any of these via the GUI, use the following:. The matrix is also referred to as [D]. Applying a tutoroal to a piezoelectric material creates a displacement, and vibrating a xnsys material generates a voltage. The analysis may be static, modal, harmonic, transient, or prestressed modal, harmonic, or transient.
Piezoelectric Analysis with Coriolis Effect. The following related topics are available: Once modelled everything, I used a APDL command to give some piezoproperties to the body which represents the piezo patch.
Both the [e] and the [d] matrices use the data table input described below:. Hot Topics 1 So I have serious problem with one nut for engine and it does ;iezoelectric want to create a sphere feature.
I also see very few nodes in your mesh, regardless of whether tuorial or quadratic elements are used. Dear Paolo, When bending solid elements, it is required to have two or more elements through the thickness. This means that you need to transform the matrix to the input order by switching row data for the shear terms as shown below:.
Any ideas of why this could happen? For modal analysis, Block Lanczos is the recommended solver. Please follow these directions to attach an archive to your reply. Permalink 1 0 0.
Pizoelectric bending solid elements, it is required to have two or more elements through the thickness. Permalink 0 0 0. This 6 x 3 matrix 4 x 2 for 2-D models relates the electric field to stress [e] matrix or to strain [d] matrix.
