| چکیده | ||
| In this article, an analytical solution is developed to study the free vibration analysis of functionally graded rectangular nanoplates. The governing equations of motion are derived based on second order shear deformation theory using nonlocal elasticity theory. It is assumed that the material properties of nanoplate vary through the thickness according to the power law distribution. Our numerical results are compared with the results of isotropic nanoplates and functionally graded macro plates. The effects of various parameters such as nonlocal parameter and power law indexes are also investigated. | ||
