For this purpose the Accepted 4 June 2018 nonlocal elasticity and Kirchhoff theories were applied to analyze the small-scale effects on Available online the armchair monolayer graphene nanoplates and obtain the static equation of the graphene 4 June 2018 Keywords nanoplates respectively. As there were no readily accurate answers to the analyses of all the Graphene problems associated with nanoplates of different boundary and geometrical conditions Rectangular nanoplate numerical methods were employed for obtaining approximate responses. One of the capable Nonlocal elasticity theory approaches to the analyses of the differential equations governing these types of plates is the DLSM meshless method. In this research the Discrete Least Squares Meshless DLSM method was employed for the static analysis of rectangular nanoplates with different boundary conditions besides assessing the effect of nonlocal coefficient amount on the nanoplate deflection. According to the results of this investigation it could be concluded that the method utilized here was suitable for solving the problems of nano-dimensions compared to the analytical and Galerkin meshless methods. 2018 Growing Science Ltd.
