“…The phenomenon has been studied by the force constant model (Gartstein et al, 2003), the nonlinear atomistic-continuum model (Chandraseker and Mukherjee, 2006;Mu et al, 2009), the molecular dynamics simulations (Liang and Upmanyu, 2006;Zhang et al, 2008), and the nonlinear stick-spiral model . Here, we present concise expressions for these coupling effects at small strains.…”

“…Torsion angle per unit length increases when the strain increases in tension. However, with increasing strain under compression, the torsion angle firstly increases, then decreases to zero, and increases again after changing the direction of twist [11]- [13].…”

“…Proračuni bazirani na dvodimenzionalnom kontinualnom modelu [19] su predvideli linearno I ⇒ T sprezanje, za male napone. Novije analize bazirane na molekularnoj dinamici [20,23], ukazuju na asimetrično ponašanje pri većim naponima. Njihov model je primenljiv na tube do 7.5 nm dužine.…”

“…Naši rezultati za I ⇒ T kod tuba iz familije (8, 2i) se kvalitativno slažu sa ranije sprovedenim MD proračunima [20,23], posebno sa drugom referencom: za mala podužna sabijanja promena znaka indukovane torzije se javlja na ε z ≈ −0.8 %. S'obzirom na jako male vrednosti indukovane torzije, razlika verovatno potiče zbog različitih početnih (relaksiranih) konfiguracija nanotuba.…”
