On the Theory of Amplitude Defining Equations of Physically Nonlinear Inelastic Piezoelectric Bodies under Monoharmonic Loading

摘要

On the basis of representation of nonlinear constitutive equations of viscoelastic piezoelectric materials under monoharmonic loading in potentials it is supposed that energy characteristics (electromechanical energy dissipated and accumulated for the period of oscillations) depend on the corresponding energy characteristics of linear theory. This allows one to transfer the results of unidimensional experiments to the complex electromechanical state.
