“…Seher et al presented the theoretical background and numerical simulations of the diffuse ultrasound [17], and In et al validated the diffuse ultrasonic method to measure the depth of a vertical crack in concrete beams [18]. Chen et al examined that the fully noncontact second harmonic generation (SHG) technique using ultrasonic transducers was promising for the feasibility of detecting the crack characterization of concrete [19]. AE is one of the nondestructive evaluation (NDE) techniques that can be applied to monitor crack in concrete structures.…”

In this paper, the authors present a stress wave-based active sensing method to detect the crack in FRP-reinforced concrete beams. The embedded smart aggregates (SAs), which utilize Lead Zirconate Titanate (PZT) as transducers, are employed in this research to generate and sense the stress wave. Three specimens are involved in the experimental program and each is made of concrete, longitudinal distributed reinforcement, steel stirrups, main bar (FRP bar or steel bar), and four SAs. A pair of SAs installed on the lower part of the main bar and the other pair of SAs mounted on the upper part of main bar are utilized to monitor the crack occurrence and development in the three test specimens. The signals received by the SA sensors are analyzed in both time domain and frequency domain. The wavelet packet energy is used to extract damage features. The applied load–vertical displacement curves of mid-span in the specimen are obtained. Experimental results show the test specimens experience crushing failure when the concrete compression exceeds its compressive strength. Increasing the contact area between FRP bar and concrete can effectively improve the cracking load of the FRP-reinforced concrete beam and reduce the cracking speed and depth of FRP-reinforced concrete beam; on the other hand, increasing the elastic modulus of the main bar can slow down the crack development of concrete on the upper side of the main bar and decrease the displacement of reinforced concrete beam during the loading test process. The research results show that the developed piezoceramic-based active sensing method, though low-cost, can monitor the crack-induced damage and estimate the process of damage degree in real-time, and has potentials to provide an early warning of crack occurrence and development for FRP-reinforced concrete beams.

“…[33][34][35] Chen et al, 36 Mahadevan et al 37 and Karve et al 38 investigated the vibro-acoustic modulation techniques, such as IM and VM method, in identifying damages caused by the alkali-silica reaction in cement-based materials. Chen et al 39 found that the VM method is effective in evaluating the progression of concrete cracks in concentrated form and distributed form. 39 Miró et al 40 developed a VM method, in which both input pump and carrier signals were ultrasonic waves to detect different levels of corrosion at steel rebar in reinforced concrete.…”

This study proposes an amplitude-modulation vibro-acoustic (AMVA) technique to track the evolution of thermal damage in pristine graphene mortar. In the proposed amplitude-modulation technique, the pump wave is amplitude-modulated using three different methods: (1) the pure amplitude-modulated (PAM) method, (2) the suppressive amplitude-modulated (SAM) method and (3) the transmitted amplitude-modulated (TAM) method. The nonlinear parameters [Formula: see text], [Formula: see text] and [Formula: see text] corresponding to the PAM, SAM and TAM methods, respectively, are theoretically established and experimentally demonstrated that the nonlinear parameters associated with the material nonlinearity, and they can be used to quantitatively characterize different damage stages of thermal damage. Meanwhile, the resonant frequency (RF) and ultrasonic pulse velocity (UPV) tests are conducted. The linear measurements, dynamic elastic modulus [Formula: see text] obtained from RF test and ultrasonic pulse velocity [Formula: see text] collected by UPV test, are used to compare with the nonlinear parameters. The results show that the proposed AMVA technique is more sensitive and feasible to serve as the tool for thermal damage detection in cement-based material compared with the conventional RF and UPV techniques.

“…The vibro-acoustic technique is one of the promising techniques for damage detection in cement-based material since the low-frequency (LF) pump wave can provide an intensive field to perturb the defects and cracks while the high-frequency (HF) probe wave is sensitive to microscale damages because of its small wavelength [4][5][6][7]. The interaction of the pump wave and probe wave in the nonlinear system, which contains distributed nonlinearity or localized nonlinearity, reveals as sidebands in the frequency spectrum.…”

Abstract. This paper proposes a new amplitude-modulation vibro-acoustic (AMVA) technique to detect thermal damage in pristine graphene (PRG) mortar materials. A new third-order solution for an amplitude-modulated low-frequency pump wave and a high-frequency probe wave in infinite isotropic material is presented. The solution includes higher-order sidebands generated by intrinsic and acquired nonlinearities. A nonlinear parameter is defined according to the third-order solution to assess the different levels of thermal damage. The experimental study demonstrates the sensitivity and feasibility of the AMVA technique by comparing the nonlinear parameter with the linear measurements of the ultrasonic pulse velocity (UPV) test. The results show that the proposed AMVA technique is a potential tool to detect and monitor thermal damage in cement-based structures.
