We present a quasi-continuum thermomechanical model for nanostructures. The model accounts for both thermoelastic and Akhiezer energy dissipation mechanisms. The model provides reasonably accurate results compared to MD simulations. Size, surface-volume ratio and vibrational mode have significant effects on damping.
