Some New Approximate Solutions in Closed-Form to Problems of Nanobars

Following recent technological advancements, a great attention has been paid to mechanical behaviour of structural elements nanosize. In this study, some solutions problems bars nanosize is examined using Eringen’s two-phase nonlocal elasticity. Assuming the fraction coefficient part material small, perturbation expansion with respect it performed. With procedure, original problem broken into set local elasticity problems. Solutions example nanobars are provided in closed-form for first time, and commented on. The new herein may well serve benchmark studies, as identification parameters nano-sized elements, such carbon nanotubes.
