“…Nowadays surface waves are also widely used in the theory and practice of non-destructive evaluation, see e.g. Gudra & Stawiski (2000). Another recent application is associated with cloaking of surface waves and seismic metamaterials, see Brulé et al (2014) and Colombi et al (2016).…”

Abstract:Explicit asymptotic formulations are derived for Rayleigh and Rayleigh-type interfacial and edge waves. The hyperbolic-elliptic duality of surface and interfacial waves is established, along with the parabolic-elliptic duality of the dispersive edge wave on a Kirchhoff plate. The effects of anisotropy, piezoelectricity, thin elastic coatings, and mixed boundary conditions are taken into consideration. The advantages of the developed approach are illustrated by steady-state and transient problems for a moving load on an elastic half-space.

The scope of this paper is to study the sulphate attack on concrete with new testing methods based on vibrational spectroscopy with mechanical waves. These are based on Non-linear Impact Resonance Acoustic Spectroscopy (NIRAS) that allows detecting the frequency shift of its resonant modes. Both, signal quality factor and alpha, are measured to monitor the increase of the non-linearity of the material due to the stiffness change on the matrix after being attacked. Different Portland cement matrices were assessed and results between vibrational tests and the traditional expansion ASTM method were compared. Two types of cement with different C 3 A content were tested for external sulphate attack and one cement with high C 3 A content with different amount of addition of SO 3 on the original mix was tested for internal attack. NIRAS was suitable for monitoring external sulphate attack process. A microstructual analysis was carried out with thermogravimetry (TG), scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques in order to detect harmful products on damaged series.

Abstract. The paper presents theoretical and experimental research of an electrical response to the elastic impulse excitation of concrete samples. The authors describe three-dimensional modeling and 3D visualization of wave processes and calculate the parameters of an electrical signal from defect-free and defective samples. The research demonstrates the comparison of design data with experimental outcomes; good precision of data was obtained.
