MATERIAL
ASSIGMENT
Piezoelectric Materials
Data -> Materials -> Piezoelectric -> PZT4 -> Assign
-> Surfaces -> Pick a Surface
Click Draw -> All materials -> Check the material is assigned as
PZT4
BOUNDARY
CONDITIONS
Potential
on the Line
Data -> Conditions -> Lines -> Potential 0.0 (or Ground
in ATILA 5.2.4 or higher version) -> Assign the right line-> Potential
1.0 -> Assign the left line
Polarization
on the Surface
Data -> Conditions -> Surfaces -> Geometry -> Polarization
(Cartesian) -> Define Polarization (P1)
We take the P1 right-ward along x [Local axis
(1,0,0)]
Choose 3PointsXZ -> Define X axis by putting (0,1,0) -> Then
define Z axis by putting (1,0,0) -> Escape
Assign Polarization (Local-Axes P1) -> Choose the surface -> Finish
To check the assignment -> Draw -> All
the conditions -> Include Local axes
Mechanical
Constraints on the Symmetrical Axis
This is the important technique for the 2D
modeling.
Data -> Conditions -> Lines -> Line-Constraints -> Choose
X-component "None", Y and Z-components "Clamped" -> Assign
the bottom line (The symmetrical line should
be taken on the X axis).
