Abstract

The analysis of a phenomenological model of the baroelectric effect, developed in the works of Professor V.I. Grigoriev, is carried out. This model comprises two sets of equations: those describing the motion of volume elements within a solid, and a phenomenological equation determining the electric charge density induced in conductors under the influence of an inhomogeneous voltage. The latter can be expressed in two forms: one in which the electric charge density generated in electroneutral conductors requires a non-zero surface charge density, and another in which the surface charge density is zero for any pressure distribution along the conductor. In Professor V.I. Grigoriev’s works, a phenomenological model of the baroelectric effect was proposed that necessitates a non-zero electric charge density on the body’s surface. The aim of this study is to investigate the baroelectric effect using a phenomenological equation that does not require surface electric charges.
