Abstract
The sound radiation and sound transmission loss (STL) characteristics of functionally graded porous graphene reinforced nanocomposite plates (FG-PGRC) are investigated based on a simple quasi-3D high order shear deformation theory (HSDT) considering bending, shear and thickness stretching effects. The Gaussian Random Field scheme theory and Halpin-Tsai micromechanical model are used to estimate the material properties of FG-PGRC plates. The governing equations are derived based on Hamilton's principle. The sound radiation and sound transmission loss of FG-PGRC plates are obtained via modal theory and Rayleigh integral method. The effects of GPL and porosity distribution patterns, weight fraction of GPLs, porosity coefficient, thickness to width ratio, damping, temperature and incidence angle on acoustic properties of FG-PGRC plates are analyzed. Results indicate that the acoustic characteristics of FG-PGRC plates are significantly influenced by above parameters. Proper design of relevant parameters can improve the acoustic characteristics of FG-PGRC plates.
