Modeling the buckling behavior of carbon nanotubes under simultaneous combination of compressive and torsional loads

Molecular dynamics simulations of structural instability of fullerene family under tension force

“…In the present study, the onset of structural instability in the fullerene is identified by a sudden/sharp drop in the strain energy as well as the axial force caused by the abrupt changes in structural configurations. The similar criterion have been widely used in the literature to determine the buckling in carbon nanotubes [35][36][37][38][39][40]. To interpret the observation of the instability in the fullerenes, it should be noted that the tensile forces applied at the upper hexagonal face of the fullerenes leads to the circumferential compressive stress.…”

Structural evolution and mechanical stabilities of head-to-side nanowelding of Cu–Ag bimetallic nanowires via atomistic simulations

“…The obtained tensile force as a function of strain (F y -e curve) can still keep the mechanical properties to present the strength of the system and this method has been successfully used in earlier studies. [50][51][52][53] 3. Results and discussion deformation focused on the boundary of the top nanowire appears and a clear junction is obtained.…”

Enhanced torsional stability of carbon nanotubes with tensile pre-strain

“…Consequently, exploring the effect of tensile pre-strain on the torsional mechanical properties of CNTs would be also very helpful to optimize the use of tensile pre-strained CNTs in new torsional devices and materials. While numerous studies have examined some aspects of the torsional mechanical properties of CNTs under uniaxial [22][23][24][25][26][27][28][29] and simultaneously combined loading [30][31][32][33][34][35][36], there is much that is still unknown about other aspects of the torsional mechanical properties of tensile pre-strained CNTs, especially concerning the chirality dependence on their enhanced torsional stability.…”
