“…It can be drawn from Figure and Equations and that

In addition, the elastic properties of the carbon nanotubes at the temperature of 800K and 1400k are calculated in the present paper, and they are compared at the temperature of 300K.…”

In the present study, a theoretical prediction of the effect of thermal environment on elastic properties of single‐walled carbon nanotubes (SWCNTs) is reported, and a molecular structural mechanics model is proposed in which the covalent bonds are traded as a truss. The influences of the temperature and the coefficient of thermal expansion (CTE) on Young's modulus and shear modulus of both armchair and zigzag SWCNTs are investigated. When CTE is 7.1×10−6K−1 and remains constant, the surface Young's modulus and the normal Young's modulus are reduced, respectively, as compared with the normal temperature. With the change of CTE, its effect on the elastic constant is far greater than the temperature effect itself. According to the principle of elastic theory, a temperature‐dependent continuum shell model of strain energy is also established. The strain energy of single‐walled carbon nanotubes decreases with the increase of the temperature.

“…From practical point of view, investigation of the thermal effects on the mechanical properties of CNTs is important because CNTs may be used in nano-engineering in various environmental temperatures [5]. More specifically, environmental conditions such as temperature and humidity have an important influence on the electrical and mechanical properties of CNTs [6].…”

“…More specifically, environmental conditions such as temperature and humidity have an important influence on the electrical and mechanical properties of CNTs [6]. So, the effects of environmental temperature on properties of CNTs have been recently studied from different aspects such as on the elastic properties [5][6][7][8], specific heat capacity [9,10], thermal conductivity [11][12][13] and thermal expansions [14][15][16].…”

A glance on the effects of temperature on axisymmetric dynamic behavior of multiwall carbon nanotubes

et al. 2012

In this paper the effects of temperature on the radial breathing modes (RBMs) and radial wave propagation in multiwall carbon nanotubes (MWCNTs) are investigated using a continuum model of multiple elastic isotropic shells. The van der Waals forces between tubes are simulated as a nonlinear function of interlayer spacing of MWCNTs. The governing equations are solved using a finite element method. A wide range of innermost radius-to-thickness ratio of MWCNTs is considered to enhance the investigation. The presented solution is verified by comparing the results with those reported in the literature. The effects of temperature on the van der Waals interaction coefficient between layers of MWCNTs are examined. It is found that the variation of the van der Waals interaction coefficient at high temperature is sensible. Subsequently, variations of RBM frequencies and radial wave propagation in MWCNTs with temperatures up to 1 600 K are illustrated. It is shown that the thick MWCNTs are more sensible to temperature than the thin ones.
