Hi all,

I'm currently doing my MSc. I've developed FEA code
for composite laminate embedded with piezoelectric
layers.

Can anybody tell me where I can find material
properties for uni-axial piezoelectric, meaning
d31(m/V) having high value comparing to than d32.

I've found some material properties in www.piezo.com.
But I'm a bit confused because they give value for d31
and d33 only. Does this means d32 is considered zero
or same as d31.

I really hope somebody can help me in this matter. My
datelini is nearing.

Best Wishes.
