High Temperature Resonant Ultrasound Spectroscopy: A Review

Figure 3

Schematic block diagram of RUS measurement and computation. (a) represents the experiment portion: prepare the sample, excite it, and detect sample resonances. (b) represents the computation portion: extract center frequencies and 𝑄𝑠, compute resonance spectrum from estimated parameters then compare it to the measured spectrum, adjust the parameters, and iterate toward a good fit to the measured spectrum so elastic constants are obtained.
