anyone suggest me where i can get the details of mathematical modelling of piezoelectric generator?

i want to do a project based on the power generation of piezoelectric devices such as piezoelectric stacks and disc. so i have to made an mathematical modelling of it. when i search for it i getting only the basic principles. can anyone suggest me how to use them to prepare my model and where i can get more details about it.

I dunno. Is the Wikipedia article on piezoelectricity
not doing it for you?
This page:
has some models too, for piezoelectric sensors.  There might be something in that article you can use.

thanks for your valuable information.
article having only basic information about it. how to develop it or where can i get the detailed information.
I am still not sure what details you are looking for.  Although I found something else on the same topic that I think is worth looking at.

This page,
shows an actual example of a piezo transducer that someone has engineered for the purposes of harvesting energy from a vibrating environment.  The specs for how that particular device works, sort of as a black box, are explained in its datasheet,

On that same page,under the tab labeled "performance", there is a graph showing the maximum amount of power they can get out of this gizmo, assuming it is "tuned" to the same frequency as the vibrations.
And it is just a few 10s of milliwatts.  I'm not sure if you're impressed by that or not.

i need details of how to calculate the power output from the piezoelectric benders or piezoelectric discs theoretically using the voltage specifications given for the device.
