This paper represents a macroscopic constitutive law for domain switching e ects, which occur in piezoelectric ceramics. The thermodynamical framework of the law is based on two scalar valued functions: the Helmholtz free energy and a switching surface. In the general sense of a kinematic hardening

## Abstract Piezoceramics are presently being used increasingly as sensors and actuators in a wide variety of electromechanical applications, for instance, piezoelectric fuel injectors in common rail diesel and gasoline engines. We will introduce the basic mesoscopic domain mechanisms typical of th
## Abstract Ferroelectric materials are characterized by interaction‐effects of mechanical and electrical fields due to different polarization directions of the unit cells. The relations between polarisation and electric field and mechanical strain and electric field respectively can be described b
We were interested in investigating the behaviour of a cardiac electrophysiological model including coupled pacemaker (PM) and nonpacemaker (NPM) cells. To this aim, a modified version of the model of Van Capelle and Durrer was used. First, few discrete values were assigned to coupling resistance (C
