“…The properties of small scale structures are significantly affected by size effects of the material, which can only be described using non-classical elasticity theories involving length scale parameters. Thus nonlocal elasticity (NE) (Eringen, 1967), modified strain gradient theory (MSGT) (Lam et al, 2003) and modified couple stress theory (MCST) (Yang et al, 2002) are developed to investigate the behaviors of micro/nano structures, such as nanobeams or nanoplates (Arshid et al, 2021; Dehsaraji et al, 2021; Khaje Khabaz et al, 2020; Luo et al, 2021; Ong et al, 2021; Tao and Dai, 2022; Zhang et al, 2017). Based on the MCST and the sine plate theory, Li and Pan (2015) analyzed the free vibration and static bending of piezoelectric FG microplates.…”

Based on the hyperbolic tangent parabola mixed shear deformation theory, the paper studied the sound radiation and the sound insulation of the functionally graded (FG) sandwich microplates under thermal-electric effects. The sandwich plate is composed of piezoelectric skin layers and FGM core layer. By using Hamilton’s principle, a size-dependent model considering the thermal-piezoelectric effects are established. The acoustic response and sound insulation are calculated with Rayleigh integral and solid-fluid coupling conditions. The accuracy of the presented method is verified by the numerical simulations. Then the effects of various parameters on the vibro-acoustic characteristics are analyzed and discussed. Numerical results show that the temperature variations, the length scale parameter to thickness ratio and the gradient index have great impacts on the FG sandwich microplates.
