| Popis: | Theories whichconsider small scale effect have a great importance on analysis in micro andnano scale. In present paper, three kind of nanotubes (Carbon Nanotube (CNT),Boron Nitride Nanotube (BNNT), and Silicon Carbide Nanotube (SiCNT)) are analyzedin case of buckling on two parameters elastic foundation. Three different smallscale theories (Nonlocal Elasticity Theory (NET), Surface Elasticity Theory(SET), and Nonlocal Surface Elasticity Theory (NET&SET)) are applied tocalculate the buckling loads. Also Classical Euler-Bernoulli Beam Theory (CT)is used to see the effect of small scale effective theories. Comparative resultsare given for simply supported nanotubes in figures. |
