On the effect of thermal depolarization and thermomechanical dependence on harmonious oscillations and dissipative heating of conic piezoceramic shells

摘要

The present paper studies electromechanical harmonic oscillations of pieoactive conic shells with regard for the temperature dependence of electromechanical characteristics and particular material depolarization in some areas of shell where the heating temperature is equal to that of the phase transition-Curie temperature. The temperature frequency dependences for various loading histories and heat boundary conditions have been obtained, the influence of depolarization processes on the electromechanical coupling coefficient has been established.
