Abstract

Buckling behavior of a bonded, uni-axially compressed double-nanoplate-system is investigated in this work. Both the synchronous and asynchronous-type buckling is considered in detail. The two nanoplates are assumed elastically bonded by a polymer resin. The nano-scale effects of nanoplates are dealt with in the analysis by using nonlocal elasticity theory. The theory is utilized for deriving the expressions for a buckling load of a double-nanoplate-system. A simple analytical method is introduced for determining the buckling load of a nonlocal double-nanoplate-system. Explicit closed-form expressions for the buckling load are derived for the case when all four ends are simply supported. Single-layered graphene-sheets are considered for the study. The study highlights that the nonlocal effects considerably influence the buckling behavior of the double-graphene-sheet-system. Unlike the buckling behavior of a single graphene sheet, the double-graphene-sheet-system undergoes both synchronous as well as asynchronous buckling. The nonlocal effects in the double-graphene-sheet-system are higher with increasing values of the nonlocal parameter for the case of synchronous buckling modes than in the asynchronous buckling modes. The increase of the stiffness of the coupling springs in the double-graphene-sheet-system reduces the nonlocal effects during the asynchronous modes of buckling. Different aspect ratios of the double-graphene-sheet-system and higher buckling modes are also considered in the work.
