This paper presents an analytical study on the buckling of orthotropic double- nanoplate-system (DNPS) subjected to biaxial compression using the two-variable refined plate theory and nonlocal elasticity theory. The two - variable refined plate theory takes into account the effects of small scale and transverse shear strains through the thickness of the nanoplate. The theory assumes parabolic distribution of the transverse shear strains through thickness of the nanoplate and does not require shear correction factors. Derived nonlocal governing equations are based on the nonlocal theory and the principle of virtual displacements. The expression for buckling load of a simply supported orthotropic DNPS was derived using the Navier's method.
