摘要：
Thermo-electro-mechanical vibration of piezoelectric nanoplates embedded in viscoelastic medium was investigated via nonlocal elasticity theory. Considering nonlocal effect, piezoelectric effect, viscoelasticity of surrounding medium and thermo-electro-mechanical loadings simultaneously, governing equations of piezoelectric nanoplates were derived, and the natural frequencies were obtained by introducing the Galerkin strip distributed transfer function method. The developed model was validated by comparing the obtained results with those available in literature. The influences of nonlocal parameter, boundary conditions, external electric voltage and increment temperature were also examined in detail. The results demonstrate the efficiency of the developed model for thermo-electro-mechanical vibration analysis of piezoelectric nanoplates embedded in viscoelastic medium. © 2020, Editorial Office of Journal of Vibration and Shock.
