“…The analytical and numerical results from the literature are related to the evaluation of the elastic properties of only non-chiral SWBNNTs with the exception of the work by Yan et al [36], who reported shear modulus results for chiral SWBNNTs (see Table 8). Most of the works cited in Table 8 deal with the evaluation of Young's modulus of SWBNNTs, and with regard to the evaluation of their shear modulus and Poisson's ratio, the available results are considerably scarcer.…”

“…Similar to the studies focused on the mechanical characterization of CNTs, those regarding the BNNTs' mechanical behaviour are predominantly carried out resorting to theoretical (analytical and numerical) methods due to the high cost and high resource of experimental procedures at the nanoscale. As with carbon nanotubes, three classes of the theoretical approaches have been used to model and characterize the mechanical behaviour of BNNTs, namely, the atomistic approach, which comprises ab initio [20] and molecular dynamics (MD) [3,[21][22][23][24][25][26], the continuum mechanics (CM) approach [27,28] and the nanoscale continuum modelling (NCM) approach, also called molecular structural mechanics (MSM) [29][30][31][32][33][34][35][36]. Among the works in which atomistic modelling was used, the elastic properties of BNNTs were accessed with recourse to MD simulations using different analytical or empirical potential functions for describing the interactions between boron (B) and nitride (N) atoms in the nanotubes.…”

“…Additionally, within the framework of NCM/MSM approach, Yan and Liew [29] considered a representative cell built by B atom connected to three neighbouring N atoms by B-N covalent bonds to construct the BNNT model, and then, the structural mechanic parameters were determined by minimizing the potential of the representative cell. Yan et al [36] studied longitudinal and torsional free vibrations of BNNTs under the NCM/MSM approach coupled with the Euler beam model and obtained analytical solutions for fundamental frequencies and shear modulus.…”

The elastic properties of chiral and non-chiral single-walled boron nitride nanotubes in a wide range of their chiral indices and diameters were studied. With this aim, a three-dimensional finite element model was used to assess their rigidities and, subsequently, elastic moduli and Poisson’s ratio. An extensive study was performed to understand the impact of the input parameters on the results obtained by numerical simulation. For comparison, the elastic properties of single-walled boron nitride nanotubes are shown together with those obtained for single-walled carbon nanotubes.

This paper deals with the free vibration analysis of a smart polymeric composite sandwich micropanel made of polyvinylidene fluoride reinforced by single-walled boron nitride nanotubes resting on an elastic substrate under an electric field. The analysis procedure is based on the first-order shear deformation theory and modified strain gradient theory to investigate the size-dependent effect. The nanotubes are assumed to be uniformly distributed within the polymeric matrix. The elastomeric substrate is modeled using Winkler springs and a Pasternak shear layer. First, the constitutive equations of the nanocomposite are derived for a unit cell using a micro-electromechanics modeling technique, and the stress–strain relations are subsequently obtained with regard to mechanical and electrical terms. The equations of motion of the micropanel are obtained based on the Hamilton principle. Finally, the natural frequencies of the micropanel are obtained by extracting the mass and stiffness matrices through the method of variational calculus. A parametric study is further performed to investigate the effect of various parameters such as the stiffness of the elastic medium, the effect of electric field, different modes of vibration, aspect ratio, and so on. It is observed that the panel’s stiffness and, consequently, the natural frequency decrease as the aspect ratio increases and the nanotube volume fraction reduces. A comparison is also conducted with the classical continuum theory and modified coupled stress theory.

Nanotube (such as carbon and boron nitride nanotubes) is a key component of modern technology applications of nanostructures due to their unique mechanical, electrical, and physical characteristics such as high elasticity modulus, suitable heat transfer, and electrical conductivity. Carbon and boron nitride nanotubes are among the promising choices in nano-fluidic, gas storage, and drug delivery systems due to their hollow cylindrical shape and appropriate chemical, mechanical, and physical properties. Thermal vibration assessment should be conducted on fluid-conveying carbon nanotubes since the effect of thermal fluctuations on the mechanical characteristics of nanostructure are significant. Previous studies have revealed that when thermal vibration is taken into account, quantum effects can become extremely important in nanoscale electronics and structures. Hence, the present review focuses mostly on previous work on fluid-conveying nanotubes and the dynamical characteristics of size-dependent vibration and non-local strain gradient theory of fluid-conveying nanotubes. Furthermore, a special effort is made to address recent and rare investigations on the vibration of fluid-conveying nanotubes in thermal environment, as well as thermal vibration concerns of carbon nanotubes.
