摘要：
In this study, the buckling behavior of orthotropic rectangular nanoplate is studied. Nonlocal elasticity theory has been implemented to investigation the shear buckling of orthotropic single-layered graphene sheets (SLGSs) in thermal environment. Using the principle of virtual work, the governing equations are derived for the orthotropic rectangular nanoplates. Differential quadrature method (DQM) is employed and numerical solutions for the critical shear buckling load are obtained. Six boundary conditions are investigated. The influence of surrounding elastic medium, temperature change, material properties and effect of boundary conditions on the shear buckling analysis of orthotropic SLGSs is studied. Numerical results show that the critical shear buckling load of SLGSs is strongly dependent on the small scale coefficient. (C) 2013 Elsevier Ltd. All rights reserved.
