Damping in piezoelectric model

I would like to know examples of piezoelectric damping/loss properties which are mentioned by PZT manufacturers which can be applied in COMSOL piezoelectric modeling.

In COMSOL 5.0 there are: mechanical damping, coupling loss, dielectric loss, and conduction loss (time harmonic). Are those damping usually defined in PZT datasheets? So far it seems I can only find the dielectric loss and mechanical damping (from the inverse of mechanical quality factor) in the typical datasheet.

Thanks.
