Thermo-electro-mechanical bending behavior of sandwich nanoplate integrated with piezoelectric face-sheets based on trigonometric plate theory

Thermo-electro-mechanical bending behavior of a sandwich nanoplate is studied in this paper. The trigonometric shear and normal deformations plate theory is used to study this behavior. The core is integrated with two piezoelectric face sheets to measure or control deformations or stresses. Three-dimensional electric potential containing a linear term along the thickness direction reflects applied voltage and an unknown term along the planar coordinate is employed for this analysis. The nanoplate is subjected to a two-parameter temperature rising and an applied voltage at top of piezoelectric face-sheets. Virtual work method is employed to derive the seven governing differential equations of the system. Our numerical results indicate that the temperature rising, applied voltage and nonlocal parameter have significant effects on the deflection and electric potential.
