“…The reduction of resonance frequency in cement-based materials with the formation of defects and microcracks is well known (ASTMC666 2008;ASTMC215 2002;Selleck et al 1998;Bentahar et al 2006). This effect, as discussed in Introduction Section (Section 1) of this paper, is referred to as linear frequency shift and is the base for damage measurement technique in (ASTM C666) and is shown schematically in Fig.…”

“…These methods are based on the linear elastic assumption and the exploitation of phenomena such as the change in wave velocity, attenuation, and amplitude to evaluate the damage (e.g., Antonaci et al 2013;Bentahar et al 2006;Selleck et al 1998;Punurai et al 2007;Avanesians and Momayez 2015). Examples of these methods include the classical ultrasonic pulse velocity (UPV) and active acoustic emission (Ghasemzadeh et al 2016;Ghasemzadeh and PourGhaz 2014;Kim and Weiss 2003;Farnam et al 2014).…”

“…Nowadays they play a major role in the complex process of diagnosis and monitoring of materials and structures and their use is regulated by several national and international standards, each one controlling specific applications of these techniques. More recently, the development of sophisticated theoretical models concerning the non-linear behavior of quasi-brittle materials such as concrete or rocks [1][2][3][4], and the initiation of powerful signal processing techniques [5][6][7][8][9], encouraged a novel way to approach ultrasonic techniques: the analysis of ultrasonic signals in the frequency domain. Accordingly, some Authors have proposed the spectral analysis of ultrasonic waves as a possible tool to characterize concrete behavior [1][2]10].…”

“…Indeed, the nonlinear properties of the existing microinclusions seem to be connected to the macroscopic elastic properties, which make the proposed set of elastic constants in Landau theory unable to describe the acoustic properties of microinhomogeneous media. [1][2][3][4][5] In resonance experiments, many measurements conducted on different microinhomogeneous materials have proven that both resonance frequency and quality factor are strain dependent. This dependence has been used to monitor damage as a function of the induced dynamic strain.…”
