PROBLEM - 3D Two-Layer, PZT4, 10 mm x 5 mm x layer thickness 1 mm, Interdigital Electrode


  • Composite of two different polarization layers, with an interdigital electrode configuration
  • Learn the internal stress distribution

GEOMETRY/DRAWING
Create Surface

Geometry -> Create -> Object -> Rectangle -> Enter first corner point -> 0,0 -> Enter second corner point -> 10,5 -> Enter

Divide Surface
Geometry -> Edit -> Divide -> Surfaces -> Near point -> Select the Surface -> Choose NURBS sense -> Input Near Points 1, 0 & 9, 0

Create Volumes Copy mode

Utilities -> Copy -> Surfaces -> Translation -> Second point z=1.0 -> Do Extrude Surfaces -> Select -> Multiple copies -> 1 -> After selecting the rectangular (click on the surface line) -> Finish

Geometry -> Create -> Volume -> Automatic 6-sided volumes -> 3 Volumes appear in blue lines

Utilities -> Copy -> Volumes -> Translation by 1 mm Select (Do not Extrude)

MATERIAL ASSIGMENT

Piezoelectric Materials

Data -> Materials -> Piezoelectric -> PZT4 -> Assign -> Pick Volumes
Click Draw -> All materials -> Check the material is assigned as PZT4
