PROBLEM - 3D Circular Plate, kp Mode, PZT4 = 50mm f x 1mm t


PROBLEM TYPE
Data -> Problem data -> 3D, Harmonic, Click both Compute Stress and Include Losses

FREQUENCY
Data -> Interval data (40000-55000 Hz)

CALCULATION

Calculate -> Calculate window -> Start

POST PROCESS/VIEW RESULTS

Click for Opening the Post Calculation (Flavia) Domain
Notice the new Toolbar appearance

Click Admittance/Impedance Result
Admittance Peak Point : 46000 Hz -> This peak corresponds to the First Resonance
Impedance Peak Point : 53500 Hz -> This peak corresponds to the First Anti-Resonance

Admittance Curve
Impedance curve

To take this graph out -> Go To

To obtain the more precise frequency dependence
Repeat Data -> Interval data -> Use New Interval -> Copy condition's entities from interval 1 -> Yes -> Create interval 2 -> 45000-47000 Hz

View Animation - Vibration Mode at a Particular Frequency

View results -> Default Analysis/Step -> Harmonic-Magnitude -> Set a Frequency
(Peak Point : 46000 Hz for Resonance Mode)
Double Click Loading frequency: 46000 Hz Harmonic Case -> Click OK (Single Click and Wait for a while!)

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 see the Animation
To save the GIF Animation Movie, use Save GIF, then Click after setting the file saving file.
