Torsional waves in nanowires with surface elasticity effect. (English) Zbl 1341.74133
Summary: We examine the torsional wave propagation along a micro-/nanowire with consideration of the surface elasticity effect. The surface of the wire is modeled by a two-dimensional “membrane” which is described by the surface/interface mechanics of M. E. Gurtin and A. I. Murdoch [Int. J. Solids Struct. 14, 431–440 (1978; Zbl 0377.73001)]. The wave dispersion diagram is numerically presented with the surface/size effect which is characterized by two surface/size factors. They are “dynamic size/surface factor” and “static size/surface factor”.
