Am I the right approach to enter a piezoelectric material?
My final goal is to simulate the static behavior of an embedded beam with 2 lawyers, one piezoelectric (PZT-5H) and the other no piezoelectric (copper) when I put voltage.
I tried to enter a piezoelectric material in ANSYS with piezoelectric And Mems extension.
For that, I add a new material in technical data and I write its anisotropic elasticity:
Then, I did geometry with two boxes:
In model, I assign one material to each lawyer (box):
For boundary conditions I put:
- fixed support
- piezoelectric body (with parameters of PZT-5H)
I want to observe directional displacement along z axis because I had to have this result:
Finally, I have no displacement along z axis with the simulation. And it's not normal.
Am I the right approach to enter a piezoelectric material and to put voltage?
And where do you think the problem is?
Thank you for your answers :)
