Özet
In this paper, the investigations of free vibrations are presented for the analysis of isotropic homogeneous thermoelastic hollow cylinder in the context of spatiotemporal theory of nonlocal elasticity with double porosity. The governing equations are transformed into ordinary differential equations from partial differential equations using time harmonic vibration technique. Analytical results have been verified through computations and simulations for frequency shift and thermoelastic damping at various values of normalized thickness and non-locality parameter, which are derived from the analytical expressions and illustrated graphically with respect to mode number. The obtained analytical results were implemented in MATLAB software to present the numerical functional iteration method for free vibration analysis. The tabulated natural frequencies have been shown in tables which yields that the variation of vibrations go on increasing with increase in mode number. The findings of this study have potential applications in nanotechnology, smart materials, energy storage systems, biomedical implants and aerospace components.
