An Investigation into Thermal Vibrations Caused by a Moving Heat Supply on a Spinning Functionally Graded Isotropic Piezoelectric Bounded Rod

By laminating piezoelectric and flexible materials, we can increase their performance. Therefore, the electrical mechanical properties of layered materials subjected to electromechanical loads heat sources must be analyzed theoretically mechanically. Since problem infinite wave propagation cannot addressed using classical thermoelasticity, extended thermoelasticity models have been derived. The thermo-mechanical response a functionally graded (FG) rod due moveable axial source is considered in this paper, utilizing dual-phase-lag (DPL) transfer model. It was supposed that physical characteristics FG varied exponentially along axis body. Both ends hold rod, there no voltage across them. Laplace transform decoupling techniques were used obtain fields analyzed. A range heterogeneity, rotation, velocity measures compare results presented here those previous literature.
