Size Dependent Buckling Analysis of Hybrid Organic/Inorganic Nano-Sized I-Beam

Abstract

In the paper, the size dependent buckling analysis of hybrid organic/inorganic nanobeam with I cross section is investigated. Eringen's nonlocal elasticity theory is used to take the size effect into consideration. Comparative buckling loads of nanobeams for first ten modes is plotted in figure using Euler-Bernoulli theory and Eringen's nonlocal elasticity theory. Two different size parameter is used. It is clearly demonstrated that the size effect can be neglected for first modes while it is unneglectable for higher modes. Simply supported case in investigated. The advantages of I-cross section are discussed.
