Abstract: • A novel fractional thermoviscoelastic damping model is established. • Explicit formula of inverse quality factor is derived. • Various energy dissipation mechanisms are combined and analyzed. • Viscoelastic losses dominate the energy dissipation within smaller thickness. A sufficiently accurate analysis of energy dissipation is very important of the design of high-performance micro/nano-mechanical resonators. In this paper, not only the thermomechanical damping loss, but also the surface loss and material loss of the energy dissipation are considered for a micro-beam resonator. A fractional Kelvin-Voigt viscoelastic micro-beam model containing memory-dependent heat flow and size effects of dissipative surface stress is first proposed. The heat flow in the micro-beam is described by a memory-dependent heat conduction model which can overcome the shortcoming of the classical Fourier's model. The analytic expression for the inverse quality factor Q − 1 is derived by the energy dissipation approach. The emphasis of the analysis is focused on the combined effects of the size-dependent surface dissipation and memory-dependent heat flow. The obtained results imply that the thermomechanical damping loss plays a significant part in Q − 1 for the larger thickness, whereas the size effect of dissipative surface stress dominate the energy dissipation for the smaller size.
