On the higher-order thermal vibrations of FG saturated porous cylindrical micro-shells integrated with nanocomposite skins in viscoelastic medium
文献摘要：
Since the multi-layered structures are widely used nowadays,and due to interesting applications of cylindrical shells,this study is dedicated to analyzing free vibrational behaviors of functionally graded saturated porous micro cylindrical shells with two nanocomposite skins.Based on Biot's assumptions,constitutive relations for the core are presented and effective properties of the skins are determined via the rule of mixture.A sinusoidal theory is used to capture the shear deformation effects,and to account for the scale effects,the modified couple stress theory is employed which suggests a material length-scale parameter for predicting the results in small-dimension.With the aid of extended form of Ham-ilton's principle for dynamic systems,differential equations of motion are extracted.Fourier series functions are used to obtain natural frequencies and after validating them,a set of parametric studies are carried out.The results show the significant effects of porosity and Skempton coefficient,pores place-ment patterns,CNTs addition and distribution patterns,temperature variations,material length-scale parameter and viscoelastic medium on the natural frequencies of the microstructure.The outcomes of this work could be used to design and manufacture more reliable micro cylindrical structures in thermo-dynamical environments.
