source arising from the viscous dissipation. This result has been noted by Lamb5 (p. 646). The error in equation (7) can thus be considered as arising from neglecting the heat produced by viscous dissipation of the kinetic energy. 1 Margules, M., Met.

We have used optical drive and detection to study dissipation in silicon nitride beam resonators. We are able to tune resonant frequency as well as quality factor in a given nanostring resonator by several hundred percent by tuning the stress in real time, providing a unique look into the sources of dissipation for this class of nanoresonator. A record room temperature quality factor of 390,000...

In this paper, by introducing a different distribution function and starting from the Boltzmann equation as well as the Maxwell-Boltzmann distribution, we obtain a Boltzmann Bhatnagar-Gross-Krook (BGK) equation for thermal flows with viscous heat dissipation in the incompressible limit. The continuous thermal BGK model is then discretized over both time and phase space to form a lattice BGK mod...

Through direct comparisons with experiments, Lefèvre et al. (Int. J. Frac. 192:1– 23, 2015) have recently confirmed the prevailing belief that the nonlinear elastic properties of rubber play a significant role in the so-called phenomenon of cavitation—that is, the sudden growth of inherent defects in rubber into large enclosed cavities/cracks in response to external stimuli. These comparisons h...
