Abstract

•Multilayer graphene nanoribbons are modeled as a single Reddy nanobeam.•Interlayer shear modulus of MLGNRs is considered as Reddy's shear modulus.•Appropriate geometrical and mechanical properties of MLGNRs are selected.•Nonlocal parameter is calibrated for the first and second frequencies of MLGNRs.•Shear correction factor of the nonlocal Timoshenko model is obtained for MLGNRs.

The aim of this study is to investigate the interlayer shear effect on nonlocal free vibration of multilayer graphene nanoribbons (MLGNRs) based on Reddy beam theory. The major novelty of the study is using the higher order shear deformation theory of Reddy to take the van der Waals’ interaction of the layers into account and calibrating the nonlocal parameter with the aids of molecular dynamics (MD) simulations to match the best results. Furthermore, the shear correction factor of nonlocal Timoshenko theory is calculated for modeling the MLGNRs. MLGNRs have broad applications in mechanical devices, such as resonators, sensors and actuators. Accordingly the present results can be used as a reference for future works in which the interlayer shear effects has substantial influences on the mechanical behavior of MLGNRs. The present study outstands for its modeling simplicity and low computational time and cost as well as excellent accuracy.
