Governing equation of motion of multiwalled carbon nanotube is obtained using Eringen's nonlocal elasticity theory. The effect of van der Waals interaction coefficient is considered between inner and outer nanotubes. Dispersion relations are obtained and discussed in detail. Effect of nonlocal parameter and van der Waals interaction to the torsional wave propagation behavior of multiwalled carbon nanotubes is investigated. It is obtained that torsional van der Waals interaction between adjacent tubes can change the rotational direction of multiwalled carbon nanotube as inphase or anti-phase. The group and escape velocity of the waves converge to a limit value in the nonlocal elasticity approach.en10.1007/s00339-016-9751-1info:eu-repo/semantics/closedAccessContinuum-MechanicsVelocityMicrotubulesBearingElementStressModelArticle1223Q3WOS:0003710417000782-s2.0-84959290678Q2
