“…So, to reduce the resistance value, the distance between the electrodes can be reduced by increasing the number of pairs of electrodes. Besides, Civalek et al [27] have studied the free vibration analyses of embedded carbon and silica carbide nanotubes lying on an elastic matrix based on Eringen's nonlocal elasticity theory. Also, they found that in the continuous systems especially like beam and rod, the decrease in vibration frequency appears with the reducing of the rigidity of structure [28].…”

“…Three analytical studies can also be found [18–20]. Some researchers have investigated micro‐ and nanobeams as well [21–26]. There are no reviews available studying the effect of imperfections, the damage location and the severity of the damage of the functionally graded material coating.…”

In this paper modal analysis is performed on a symmetric aluminum beam which is coated with functionally graded material containing porosities. A polynomial function is used to vary the density and elasticity through the thickness of the coating, while the effective elastic modulus and density are found with classical lamination theory. To achieve a truthful modeling the gradually changing mechanical properties of the coating are modeled as 25 layers of material, while each individual layer is isotropic and homogeneous. MATLAB is used to write a finite element code and Timoshenko beam elements are used to include shear deformation effects. To show the influences of crack location, crack depth, porosity and the polynomial function index on the natural beam frequencies a parametric study is conducted. Multiple boundary conditions were also considered and it was found that the natural frequency values were significantly affected by the studied parameters.

“…Civalek presented the finite element formulations of plates and shells [37]. On the other hand, it can be stated that studies on the use of finite element formulation in mechanical analysis of nanostructures with nonlocal elasticity have taken place in the literature [27,28,[38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. Additionally, the free vibration behavior of a functionally graded beam is researched for Euler-Bernoulli, Timoshenko, Shear and Rayleigh beam theories [53].…”

Zinc oxide nanowires (ZnO NWs) can be used in some NEMS applications due to their remarkable chemical, physical, mechanical and thermal resistance properties. In terms of the suitability of such NEMS organizations, a correct mechanical model and design of ZnO NWs should also be established under different effects. In this study, thermal vibration analyses of elastic beam models of ZnO NWs are examined based on Eringen's nonlocal elasticity theory. The resulting equation of motion is solved with a finite element formulation developed for the atomic size-effect and thermal environment. The vibration frequencies of ZnO NWs with different boundary conditions are calculated under nonlocal parameter and temperature change values and numerical results were discussed.
