文摘

Free vibration of three-dimensional anisotropic layered nanoplates is studied. Final equation of motion is reduced to an eigen-system via Fourier series expansion. Natural frequency and mode shape are derived by propagator matrix method. Effect of nonlocal parameter and stacking sequence on sandwich plates is analyzed. Results can serve as benchmarks to thick-plate theory and other numerical methods.
