摘要：

The influence of surface stress on the resonance frequencies of bending nanowires was studied by incorporating the generalized Young-Laplace equation into Euler-Bernoulli beam theory. Theoretical solutions are presented for three different boundary conditions. The overall Young's modulus was used to study the surface stress influenced mechanical behavior of bending nanowires and a comparison was made for the overall Young's modulus calculated from nanowires in resonance and static bending. It was found that the overall Young's modulus can be simply related to a nondimensional surface effect factor via empirical formulae.
