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.

A comprehensive review of destructive testing techniques to understand concrete behavior is presented in this work. The main objective of this article is to summarize the literature from the last three decades related to the following topics: 1) the size effect in plain and reinforced concrete, 2) the crack estimation and propagation in concrete under various loading conditions, 3) the determination of material properties of concrete using triaxial testing techniques, 4) the behavior of concrete under creep and early age shrinkage which eventually affect the properties of concrete and lastly 5) the strain rate effect in concrete using various experimental techniques such as Split Hopkinson pressure bar, impact loading, drop hammer and the literature related to cyclic loading on concrete. The scope of the presented work is limited to destructive testing related to the topics defined above. To completely understand the behavior of material, at least three aspects must be required: the material’s theoretical basics, experimental validation, and numerical implementation. The authors presented the review articles related to theoretical basics and numerical implementation in parts I and II of this article. The presented work is part III, which is related to experimental work. In the upcoming section, the research related to specific topics is presented, and a summary is provided at the end of each section. Finally, the future works and the research directions are shown in the conclusion section.

Nonlinear wave mixing provides a potential method to evaluate localized micro-damage in structures. The wave mixing technique has some unique advantages over the nonlinear ultrasonic technique based on the higher harmonic generation, such as frequency selectivity, which can separate harmonic components generated due to instrumentation. In this paper, we numerically studied the frequency mixing response induced by the nonlinear interaction of two primary Rayleigh waves in a concrete material. The nonlinearity considered in the present study is due to crack-wave interaction, which is often called contact acoustic nonlinearity (CAN). A limited number of experimental studies were conducted on concrete prisms to evaluate surface cracks. Both numerical and experimental results illustrate the generation of the second-and thirdorder combined harmonics, which can be utilized to detect and localize subsurface cracks in concrete structures. The newly discovered third-order combined harmonics, which result from the mutual interaction between the primary Rayleigh waves and their induced second-harmonic waves, can be exploited to characterize micro-damage in various applications.
