“…The bonded area was 100 mm × 90 mm on each surface of the concrete cube and the lap-joint thickness was about 1 mm. reported The examples of their application include monitoring of damage in concrete samples [27], reinforced concrete beams [28][29][30] or in an adhesive lap joint of metal elements [31]. However, the literature on the inspection of steel-concrete adhesive joints using ultrasonic waves is limited.…”

Adhesive bonding is increasingly being incorporated into civil engineering applications. Recently, the use of structural adhesives in steel-concrete composite systems is of particular interest. The aim of the study is an experimental investigation of the damage assessment of the connection between steel and concrete during mechanical degradation. Nine specimens consisted of a concrete cube and two adhesively bonded steel plates were examined. The inspection was based on the ultrasound monitoring during push-out tests. Ultrasonic waves were excited and registered by means of piezoelectric transducers every two seconds until the specimen failure. To determine the slip between the steel and concrete a photogrammetric method was applied. The procedure of damage evaluation is based on the monitoring of the changes in the amplitude and phase shift of signals measured during subsequent phases of degradation. To quantify discrepancies between the reference signal and other registered signals, the Sprague and Gears metric was applied. The results showed the possibilities and limitations of the proposed approach in diagnostics of adhesive connections between steel and concrete depending on the failure modes.

“…However, these linear features are not sensitive enough for micro damage (1,2) .Modulated ultrasonic technology is rapidly developed during last several years becuase it is more sensitive to micro damage than linear ultrasonic. (3,4,5,6) . In recent years, fiber Bragg grating (FBG) has been expected to be a valuable alternative of ultrasonic detector.…”

Abstract. This study presents a damage detection system using modulated ultrasonic and fiber Bragg grating (FBG) in Aluminum thin plate. In the system, modulated ultrasonic technology and FBG sensing technology were combined to detect damage. Piezoelectric patches used to excite ultrasonic and FBG were pasted on a Acrylic plate and then contacted with specimen by coupling, so the excitation point of ultrasonic and sensing point of FBG can be modified arbitrarily. Experiment results showed that the system can detect the damage signal more flexibly.

“…Changes in the transmission spectrum are related to adhesive properties and optimal curing time can be determined. The through transmission method can also be used to evaluate fatigue damage, which generates ultrasonic harmonics in the adhesive layer [3]. An increase in fatigue cycles is related to an increase in the acoustic nonlinearity parameter and early damage can be detected.…”
