| Abstract | ||
| In this research, thermal and electrical effects on dynamic response of a porous nano-sized plate modeled by a nonlocal higher-order refined plate model have been explored in detail. A hyperbolic shear stain function has been used. The porous material considered in this research may have uniform or non-uniform porosity distribution across the cross section. Stain gradient effects have also been considered for more accurate modeling of the scale-dependent plate. Hamilton's rule has been employed for establishing the governing equations. Derived findings by differential quadrature (DQ) method have been validated with those represented in previous researches. The effects of thermal environment, electrical environment, nonlocal scale, and porous material on dynamic behaviors of foam-based nanoplate have been explored. | ||
