Abstract

The oscillation and dissipative heating of an infinitely long piezoceramic cylinder polarized along the radius is considered in the case of partial heat depolarization, with harmonic quasi-static loading of the cylinder by a potential difference. The inner surface of the cylinder is thermally insulated; there is heat transfer at the outer surface. An analytical solution is obtained, and numerical calculations are performed for a TsTStBS-2 piezoceramic. The conditions in which the depolarized zone appears are examined, along with the stress-strain state of the cylinder.
