*PIEZOELECTRIC DAMPING

Specify piezoelectric material damping for a piezoelectric material.

This option is used to provide piezoelectric material damping for mode-based analyses and for direct-integration steady-state analysis in Abaqus/Standard.

It is relevant only for piezoelectric elements. You can provide damping coefficients for the displacement (mechanical), piezoelectric coupling, and dielectric parts of the damping operator.

This option is ignored in mode-based procedures that use Lanczos or subspace iteration eigenvalue extraction that does not use the SIM architecture (FREQUENCY, EIGENSOLVER=SUBSPACE, SIM=NO).
