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