Abstract

Free vibration analysis of Au nanowires has been investigated. Au
nanowire is modeled via thin beam using the linear theory. Three-different
cross-sections such as circular, rectangular and triangular are taken into
consideration for ultra thin nanowires. Frequency values have been obtained for
different geometric parameters and simply supported of boundary condition. This
study is helpful for design of the nanowires based instruments in modern NEMS
technology.
