| Abstract | ||
| This paper investigates impact of thickness stretching phenomenon on the scale-dependent behavior of nano panel in electromagnetic environment in the framework of HOSNDT. Unlike classic theories of shells and plates, the radial displacement is assumed variable along the thickness direction as summation of bending, shear and thickness stretching displacements in which the last term is assumed trigonometrically variable along the thickness direction. Generalized magneto-electro-elastic equations are derived using the virtual work principle. The main novelty of the present paper is application of thickness stretching formulation on the results. The bending results are calculated using analytical method with actuating the nano panel with initial electromagnetic potentials. An extended numerical investigation is presented to examine influence of significant parameters on the static results. | ||
