Abstract

This study investigates that the sound wave propagation of Nanofibers under the influence of surface effect via piezo thermo elasticity using Timoshenko form of beam equation. The equation of analytical model is obtained for Nanofiber through shear and rotation effect. Curves are drawn for frequency, phase velocity, piezoelectric strain and dynamic displacement at different vibration modes of Nanofibers. From the result obtained, it is seen that the surface effect gives significant contribution to the physical variables. The presented study is expected to be more helpful for the design of piezo-thermo-mechanical Nanofiber-based devices.
