The Piezoelectric Material node defines the piezoelectric material properties either in stress-charge form using the elasticity matrix and the coupling matrix, or in strain-charge form using the compliance matrix and the coupling matrix. It is normally used together with a
Piezoelectric Effect, Time Explicit multiphysics coupling node and a corresponding
Charge Conservation, Piezoelectric node in the
Electrostatics interface. This node is added by default to the
Elastic Waves, Time Explicit interface when adding a
Piezoelectric Waves, Time Explicit multiphysics interface.
Select the Coordinate system that defines the polarization orientation of the piezoelectric crystal. The default is the
Global coordinate system. The polarization is defined in the local x-axis direction in 2D, while it uses the local z-axis in 2D axisymmetry and 3D.
Select a Constitutive relation as
Stress-charge form (the default) or
Strain-charge form. For each of the following, the default uses values
From material. For
User defined enter other values in the matrix or field as needed.
