“…The accurate Young's modulus measurement based on Rayleigh wave velocity using an empirical Poisson's ratio may also be possible, as described by Li and Feng [27]. In the case of orthotropic material characterization, other techniques using full wavefield data may require the use of 3D scanning laser Doppler vibrometry and improved machine learning methods for the identification of properties such as elastic stiffness [21,22].…”

“…In the last case, scanning laser Doppler vibrometry is a widely adopted method to measure the out-of-plane vibrational displacements related to the 1D wave propagation of materials for detecting defects or estimating viscoelastic parameters [15]. Recent technological developments have led to performant 3D scanning laser Doppler vibrometers, which give access to both out-of-plane and in-plane vibrational velocity components, which combined with inverse problem approaches, allow for the identification of orthotropic elastic stiffness using 3D guided wavefield data [21]. Likewise, numerical methods, including machine-learning methods (such as clustering of multivariate data series), are also actively used in applications related to material property characterization by means of elastic guided wave propagation phenomena [22].…”

Many museums have been producing reproductions for several years to replace artworks weakened by outdoor exhibition. Among these, in order to imitate the original aesthetic, the French consortium Réunion des Musées Nationaux–Grand Palais has chosen to work from large-format marble sculpture molds to complex composite materials based on resins comprising mineral fillers. However, similar to the original works of art, these reproductions age and deteriorate due to constant outdoor exposure. For this reason, current research focuses on the preventive conservation and monitoring of the structural health of these reconstructed objects. The goal of this paper was to study the resin/mineral powder composite materials used to produce cultural heritage reproductions of sculptures. This work is oriented toward a comparison of the mechanical properties of composite materials used in the replacement of cultural heritage sculptures (for instance, in the Garden of the Palace of Versailles or the Rodin Museum). The objectives were to first characterize the physical and mechanical properties of these materials in order to identify the most suitable material for cultural heritage reproduction, and secondly, to propose a method with minimal contact that obtained equivalent information as analyses performed with conventional ultrasonic techniques. These nondestructive evaluation techniques could be used for laboratory and in situ analyses. Samples of different polymer/mineral powder filler compositions were analyzed by compressional, shear and surface waves, generated by a 1 MHz center frequency ultrasonic transducer. Firstly, the measurements made it possible to evaluate the velocities of the bulk acoustic waves and extract the Young’s modulus of each tested material. Secondly, in order to have minimal contact with the analyzed structure, a laser interferometry system was used to detect waves at the surface and follow their propagation. The results clearly showed the possibility of using this technique to extract mechanical characteristics of composite materials, allowing for selection of material for the reproduction of large-format statues. For different types of polymer resins, the ability of ultrasonic analysis to track the impact of rock powder (marble or slate) on the mechanical properties of these synthetic materials was clearly observed, proving that this technique holds promise for monitoring the structural health of large-format artwork.

“…In parallel to the advancement in theoretical modeling, laser vibrometry and material characterization using this kind of instrumental system were in full development, starting with Aussel and Monchalin proposing an elastic constants determination technique using precise laser-ultrasonic velocity measurement [10]. Orta et al developed a semi-analytical finite element method to identify orthotropic elastic stiffness using 3D vibrometry measurement of guided waves [11]. Staszewski et al did an overview on the use of Laser Doppler vibrometry for structural health monitoring [2].…”

This work focuses on the monitoring of the 3D propagation of ultrasonic surface waves used in non-destructive testing and evaluation. The ellipticity of the movement related to the Rayleigh wave, specifically the H/V parameter, is studied analytically, numerically, and experimentally on an aluminum block. The study involves generating signals from the theoretical harmonic expression of particle displacement issued from Rayleigh wave, carrying out numerical simulations using a finite element method, and generating the Rayleigh wave using a shear contact transducer with a 1 MHz central frequency in the experimental study. The work also involves appropriate filtering of signals to extract components with specific polarization and suppress other modes with low polarization energy. The obtained results for aluminum show a good agreement between the analytical, numerical, and experimental studies of Rayleigh wave ellipticity. Moreover, these H/V ratios are consistent with the theoretical values described in the literature. As a proof of concept, this method is also applied to simulation data to study orthotropic materials (wood/bone), obtaining promising results.

Rayleigh wave is widely used in non-destructive testing and evaluation, the three-dimensional vibrations inspection highlights the bivariate nature of these waves and their elliptic motion. The links between this motion and the material properties are well established, however, theoretical expressions are very sensitive to the measurement errors and the purity of the surface wave. If the classical processing often uses independently the two components of the wave, it seems more complete to process the two components together using the adequate bivariant filters. This work presents the monitoring of the 3D propagation of ultrasonic Rayleigh waves and the signal processing dedicated to the identification of their characteristic parameters. It is particularly focused on the wave ellipticity, i.e. the horizontal to vertical component ratio (H/V-ratio). This phenomenon is studied analytically, numerically and experimentally. Over a scanned area, the local mechanical parameters are estimated using time signals extracted from each single point. The obtained results for Aluminum show a good agreement between the analytical, numerical and experimental studies of Rayleigh wave ellipticity. Moreover, these H/V ratios are consistent with the theoretical values found in literature. This method is also applied on simulation data to study orthotropic materials (wood/bone), obtaining promising results.
