Hi,
In ANSYS you can import material properties of piezo ceramics. But where can I find the specific material properties that are required by ANSYS?

You can find all kind of piezoelectric material properties on the net, like:

or


however, those are not compatible with what ANSYS requires. Where can I find the data that ANSYS requires?

The data that ANSYS needs:
! Material properties for PZT-4
!
mp,DENS,1,7700 ! Density, kg/m**3

tb,DPER,1 ! Relative permittivity at constant strain
tbdata,1,729,635,729
! - Alternative input of permittivity if used with SOLID5
! mp,PERX,1,729
! mp,PERY,1,635
! mp,PERZ,1,729
!
tb,ANEL,1 ! Anisotropic elastic stiffness, N/m^2
tbdata,1,13.9E10,7.43E10,7.78E10 ! c11,c13,c12
tbdata,7,11.5E10,7.43E10 ! c33,c13
tbdata,12,13.9E10 ! c11
tbdata,16,2.56E10 ! c44
tbdata,19,2.56E10 ! c44
tbdata,21,3.06E10 ! c66

tb,PIEZ,1 ! Piezoelectric stress coefficients, C/m^2
tbdata,2,-5.2 ! e31
tbdata,5,15.1 ! e33
tbdata,8,-5.2 ! e31
tbdata,10,12.7 ! e15
tbdata,15,12.7 ! e15
