I am doing modelling of piezoelectric sensor pasted on the surface of the structure. I am applying load at the top face (Z-direction) of structure and pasting PZT on Y-direction face. But for given values of d13, d23, d33, d42, d51 as -2.1e-10, -2.1e-10, 5e-10, 5.8e-10 & 5.8e-10 respectively. What changes should I make in this matrix so that polarization direction will be X or Y direction?
Any help would be appreciated.
You should use "Rotated Coordinate system". There are nice examples on the COMSOL directory. The following link explains in detail what needs to be changed to address the polarization direction.

Thank you Reza Pakdaman Zangabad sir for the help. I read it, but as I am working in Ansys apdl, so I am confused that if APDL has the same option to change the polarization axis. If Ansys APDL has that option, please help regarding the same.
If x'1=x2, x'2=x3 (polarization axis), x'3=x1, then d'12=d23; d'22=d33; d'32=d13; d'43=d51; d'61=d42.
