Abstract
Murmu et al 23 recently presented a nonlocal model for the transverse vibration of simply supported graphene sheets in the presence of a unidirectional inplane magnetic field Further studies showed that the majority of Lorentz’s force components were improperly provided and led to invalid governing equations To remove such deficiencies the most general form of Lorentz’s force components is carefully extracted in the present work The nonlocal equations of motion of the problem are reconstructed and solved again The influences of crucial parameters on the flexural frequencies of magnetically affected graphene sheets and nanoribbons are examined in detail Furthermore the crucial discrepancies between the results obtained in this study and those of the abovementioned previous work are rationally discussed Some erroneous results of the latter are also rectifiedKeivan Kiani was born in Hamedan Iran in 1979 He obtained a BSc degree in Civil Engineering from the Isfahan University of Technology in 1999 Subsequently he was awarded his MSc and PhD degrees with a major in structural engineering from the Sharif University of Technology in 2002 and 2010 respectively His current research focuses on wave propagation vibrations and dynamic instability of nanostructures using advanced elasticity theories He has published more than 45 articles in peerreviewed journals of mathematics physics and mechanics and has been the reviewer of more than 25 ISI journals
