Non-linear constitutive relations for piezoceramic materials

摘要

Piezoelectric materials produce electric charges when mechanically deformed and an electric potential causes a mechanical deformation. This property makes them suitable for sensor and transducer applications. Understanding of the electroelastic constitutive behavior is critical for predicting the response of a structure with embedded piezoelectric material. A concise formulation of relevant non-linear constitutive relations is presented in this paper.
