“…For those low Q materials such as dentin, peaks may be broad and overlap each other, which made it difficult to directly extract resonant frequencies from spectrum. Therefore linear predictive filter, an accurate signal processing method, introduced by Kumaresan, Tufts, and Lebedev et al was selected here to distinguish the resonant frequencies, which was proved to be a perfect solution [23–27]. …”

This paper proposed to take advantages of resonant ultrasound spectroscopy (RUS) to measure the mechanical properties of human dentin specimen. The resonant spectroscopy of the dentin specimen was obtained between the frequency bands 155 and 575 kHz, and resonant frequencies were extracted by linear predictive filter and then by Levenberg-Marquardt method. By inverse problem approach, 13 experimental resonant frequencies progressively matched to the first 30 orders of theoretical resonant frequencies calculated by Lagrangian variational method. The full second-order elastic tensor of dentin specimen was adjusted. The whole set of human dentin engineering moduli, including Young's moduli (E11 = 22.641 GPa, E33 = 13.637 GPa), shear moduli (G12 = 10.608 GPa, G23 = 7.742 Gpa), and Poisson's ratios (ν12 = 0.067, ν31 = 0.378), were finally calculated. This study demonstrates that RUS can be successfully adapted to measure the mechanical properties of low quality factor biomaterials.

“…The resonant-bar method is a typical resonant method based on the measured resonant frequency and the bandwidth of frequency spectrum of rock bar with regular configuration to calculate the velocity and the quality factor of the measurement samples. This method is also widely used in measurements of elastic parameters and nonlinear properties of a rock sample [11][12][13][14][15] . The merit of this method is that the measurement can be made at a frequency as low as several kHz or even lower if a longer rock sample is used.…”

Experimental studies on perturbed acoustic resonant spectroscopy by a small rock sample in a cylindrical cavity

et al. 2006

A measurement system for acoustic resonant spectroscopy (ARS) is established, and the effects of resonant cavity geometry, inner perturbation samples and environmental temperature on the ARS are investigated. The ARSs of the small samples with various sizes and acoustic properties are measured. The results show that at the normal pressure, the resonant frequency decreases gradually with the increase of liquid temperature in the cylindrical cavity, while the resonant amplitude increases. At certain pressure and temperature, both the resonant frequency and the amplitude decrease greatly when there exist air bubbles inside the cavity fluid. The ARS is apparently affected by the sample porosity and the sample location in the resonant cavity. At the middle of the cavity, the resonant frequencies reach their maximum values for all of the measurement samples. The resonant frequencies of the porous rock samples are smaller than those of the compacted samples if other acoustic parameters are the same. As the sample is moved from the top to the middle of the cavity along its axis, the resonant amplitude increases gradually for the compacted rocks while decreases for the unconsolidated rocks. Furthermore, the resonant amplitude increases firstly and then decreases if the porosity of the rock sample is relatively small. In addition, through the comparisons between the experimental and theoretical results, it is found that the effects of the acoustic parameters and sizes of the samples and the size of the cylindrical cavity on the laboratory results agree well with the theoretical ones qualitatively. These results may provide basic reference for the experiment study of rock acoustic properties in a low frequency using ARS.Keywords: acoustic resonant spectroscopy, acoustic velocity and attenuation, experiment measurement, rock acoustic property.

“…Each record in the series was processed using the algorithm described in [29,30], and the results obtained for all records in the series were averaged with the weights inversely proportional to the dispersion of the measured magnitudes [31]. The thus obtained res onance frequencies and Q factors of the mode oscilla tions represented the source data for the parameter inversion problem and determination of C ij [22][23][24]27]. The experimental data were weighted in an anal ogous manner during inversion.…”

Correlation between elastic anisotropy and magnetic susceptibility anisotropy of sedimentary and metamorphic rock

2012

A correlation has been revealed between the types of acoustic anisotropy and magnetic suscepti bility anisotropy for specimens from noncrystalline metamorphic and sedimentary rock has been revealed. This correlation makes it possible to assume that the anisotropy of magnetic and acoustic characteristics has the same origin, namely, the rock texture. The pronounced triaxial acoustic anisotropy for specimens of poly crystalline rock in the absence of external forces makes it possible to judge the fracturing caused by tectonic loads and the degree of this fracturing. The large body of available experimental data allows the expectation that it will be possible to obtain empirical dependences suitable for estimating the intensity of geological pro cesses based on the values of the magnetic susceptibility anisotropy and elasticity tensor anisotropy.
