II. How To Use ATILA 3.1
Bimorph (3) PROBLEM - 3D Rectangular Plate, PZT4 = 40mm x 6mm x 1mm x 2 pieces, Cantilever Support
MESHING
![]() Cant view is not very suitable to Meshing -> View -> Rotate -> Plane xy (original) Mapped Mesh Meshing -> Structured -> Volumes -> Select all volumes
-> Then Cancel the further process
PROBLEM
TYPE CALCULATION
Calculate -> Calculate window -> Start
POST
PROCESS/VIEW RESULTS
![]() Notice the new Toolbar appearance Click
![]() Admittance Peak Point : 4500 Hz -> This peak corresponds to the First Resonance
To take this
graph out -> Go To
View Animation - Vibration
Mode at a Particular Frequency
View results -> Default Analysis/Step -> Harmonic-Magnitude
-> Set a Frequency
(100 Hz for Off-Resonance Mode: Peak Point : 4500 Hz for Resonance Mode) Double Click ![]() Set Deformation
-> Displacement
View results -> Deformation -> Displacement
Diformation Scale Change
Click Windows -> Deform mesh -> Change
the Factor in Mesh Deformation
Other parameter than Displacement
Set Results View -> View results -> Contour
Fill -> Von Mises Stress
After setting both “Results view” and “Deformation” -> Click ![]() To save the GIF Animation Movie, use Save GIF, then Click ![]()
Comparison of the FEM Calculation with the Beam Theory The beam theory is applied for a very thin and narrow (width) beam.
