Abstract
Axial displacement and electric wave propagation of singlewalled BoronNitride nanotubes SWBNNTs induced by alternating current AC are investigated in this study A singlewalled zigzag structure BNNT is modeled based on nonlocal piezoelasticity theory and EulerBernoulli beam EBB Equations correspond to lateral displacement have been obtained Using Hamilton’s principle and considering charge equation for coupling of electrical and mechanical fields the higher order of governing equations are derived Analytical solution is applied to solve governing equations Also the axial and lateral displacement of a SWBNNT and electric potential induced by AC through it are presented The detailed parametric study is conducted focusing on the remarkable effects of the half wave number on the behavior of the SWBNNT The results indicate applying alternating field leads to propagation of axial displacement along the SWBNNT Also the result of this study can be useful to design and manufacture of smart micro/nanoelectromechanical systems in advanced biomechanics applications by controlling axial and lateral displacementsAli Ghorbanpour Arani received his BSc degree from Sharif University of Technology Tehran Iran in 1988 He then received his MSc degree from Amirkabir University of Technology Tehran Iran in 1991 and his PhD degree from the Esfahan University of Technology Esfahan Iran in 2001 Dr Ali Ghorbanpour Arani is a Professor in the Mechanical Engineering Department of University of Kashan Kashan Iran His current research interests are stress analyses stability and vibration of nanotubes and functionally graded materialsAli Hafizi Bidgoli received his BSc degree from Azad Islamic University of Kashan in Kashan Iran in 2001 He is currently a MSc student at University of Kashan Iran His research interests are stress wave propagation in carbon and boronnitride nanotubesAbbas Karamali Ravandi received his BSc degree from Isfahan University of Technology in Isfahan Iran in 2011 He is currently a MSc student at University of Kashan Iran His research interests are instability vibration and stress wave propagation in carbon and boronnitride nanotubesMir abbas Roudbari received his BSc degree from the University of shahid bahonar Kerman Iran in 2006 He then received his MScdegree from University of Guilan Iran in 2009 He is currently a PhD student at University of Kashan Iran His research interests are vibration wave propagation and buckling analyses of carbon and boron nitride nanotubes and smart materialsSaeed Amir received his BSc degree from the University of Kashan in Kashan Iran in 2007 He then received his MSc degree from University of Kashan in Kashan Iran in 2009 He is currently a PhD student at University of Kashan in Kashan Iran His research interests are buckling and vibration analyses of carbon nanotubes smart materials and functionally graded materialsMohammad Bagher Azizkhani received his BSc degree from University of Golpayegan in Golpayegan Iran in 2011 He is currently a MSc student at University of Kashan Iran His research interests are instability vibration in carbon and boronnitride nanotubes
