I would like to simulate PMNPT crystal with k33 in LE (Longitudinal Extension) mode. Can someone offer some tools or literature about that? Righ now I am trying to write it in matlab, but still don't get transfer function like in experiment. I am using matrix notation of 1D model for transmitter in frequency range. I had checked everything ten times, so looking for another way to solve this problem.

Hi Marius,
Unfortunately I don't have much experience simulating the response of piezoelectrical materials. I know there are various commercial FEM packages for this (e.g., PZFlex), but I have never used them.
