DOI: 10.1016/j.ijmecsci.2019.105094
Abstract: Abstract In this work, the thermoelastic damping (TED) effect with the time-lagging is evaluated on the micro- or nano-cylindrical shell. Especially, the mechanism should be considered for the high-frequency ranges in the ultra-low temperature. And… read more here.

DOI: 10.1016/j.tws.2020.107309
Abstract: Abstract Considering the heat-conduction dimension (HCD) and adopting the dual-phase-lagging (DPL) non-Fourier theory, analytical models of thermoelastic damping (TED) and frequency shift for the rectangular cross-section micro/nano-ring resonators are first derived in the series form… read more here.
