Effect of Power Law Index Variation on Eigen Frequency of Functionally Graded Piezoelectric Round Disc

-Piezoelectric functionally graded hollow discs are highly used materials. It makes smart devices like car hinges, drones, and microelectromechanical devices. Shear-induced eigenfrequency is much less utilized because it is very difficult to analyze. To apply functionally graded piezoelectric materials, shear vibration of the functionally graded holoow disc has been obtained by producing the d15 effect. The d15 has a higher coupling coefficient than d33 and d31, so it can be utilized to exit shear vibrations in the FGPM round hollow disc. Effect on eigenfrequency of FGPM round disk has been obtained for varying the value of power law index. The material property of the functionally graded disc varies along the thickness by helping power law. The disc is radially polarized, and an electric field is applied along the thickness.
