A novel microscopic modeling technique is proposed to study the hysteresis effects on piezoceramic materials and structures using finite element method and a modified Preisach model where polarization term is added in the constitutive relationship to describe the microscopic hysteresis effects. A simple bimorph piezoceramic beam is used as an example to illustrate the effectiveness of the present theory. The established modeling procedure is applicable to arbitrary piezoelectric structures.
