Notes:
Based on general rotationally invariant nonlinear electroelastic equations (energy balance equation and Gibbs function expansion), a complete and deductive derivation of constitutive equations for an electroelastic media upon mechanical or electrical bias has been presented. Bilinear constitutive relations for large quantities have been given and linear, but parametric constitutive formulas for small-field variables have been derived in the reference or intermediate frame. Equations of motion and boundary conditions in the respective configurations, required to solve dynamical problems, are also reported shortly for completeness. Presented reformulation of constitutive equations may be useful in solving nonlinear problems of electromechanical interactions in crystals, for example in analyzing sensors of nonelectric quantities with electric output or modulators.
