Abstract
A dissipative surface stress model is suggested to study the surface dissipation of vibrating elastic microbeams. The model is an extension of the well-known Zener model from bulk materials to the surface in the presence of an initial surface tension. Explicit formulas are derived for the frequency-dependent quality factor and the maximum surface dissipation. This model predicts a size-dependent surface dissipation when the size of the cross section downs to nanometers. In particular, the model offers plausible explanation for a few experimental phenomena reported in the most recent literature.
