Yes, every word helps and thank you so much for helping out. But in your example you had neglected capacitance which allowed you to get away with using I instead of q. I do not understand your second part. There IS a electrical forcing function (thats the point of my transducer). As I look...

For a piezoelectric crystal with a applied alternating voltage The mechanical equation is m\frac{{{d^2}x }}{{d{t^2}}} + r\frac{{dx }}{{dt}} + sx = F E= -g33.S (S=stress, piezoelectric voltage const, E=electric field) F= -A.E/g33 (A=Area of resonator, l=hieght) F= - A.V/(g33 .l)...

my piezo film is electrical to mechanical. The driving force is the applied alternating electric field which causes the vibration, so I don't think I can use D as the driving force. I will have to think of something else. By the way is this covered in standard text-books or the literature...

What exactly is this D? and shouldn't there be a term taking into consideration of capacitance?

Yes I am familiar with differential equations. I am also aware of the equation for mechanical resonance, but have little clue about electrical circuits beyond the bare basics. Please do help me along. I looked over the equation for electrical circuits (for series resonance for a start) and...

My first post here. :D usually this situation does not arise, but I am working on thin piezoelectric films. When a apply a alternating voltage on the electrodes, the film vibrates. Now this constitutes a LCR circuit which has a resonant and anti-resonance frequency. Since it is vibrating, it...
