    Abstract

    Acoustic emission is a nondestructive testing (NDT) technique, widely used to monitor the condition of structures for safety reasons especially in real time. The method utilizes the electrical signals generated by the elastic waves in a material under load to detect and locate damage in structures. However, identifying the sources of AE signals in concrete or composite materials can be challenging due to the anisotropic properties of materials and interpreting a large amount of AE data, leading to data misinterpretation and inaccurate detection of damage. Hence, the need for filtering out noise-induced signals from recorded data and emphasizing the actual AE source is crucial for monitoring and source localization of damage in real time. This study proposed a one-dimensional convolutional neural network (1D-CNN) deep learning approach to filter around 22,000 AE data in a reinforced concrete (RC) beam. The model utilizes significant AE parameters identified through neighborhood component analysis (NCA) to classify true AE signals from noise-induced signals. By using the optimized network parameters, a high classification accuracy of 97% and 96.29% was achieved during the training and testing phases, respectively. To check the reliability of the proposed AE filtering model in the real world, it was evaluated and verified using source location AE activities collected during a four-point bending test on a shear-deficient beam. The outcomes suggest that the proposed AE filtration model has the potential to accurately classify AE signals with an accuracy of 92.8% and proved that the filtration model provides accurate and valuable insight into source location determination.

    <jats:p>This research investigates the influence of the pre-existing defects within concrete taken from the in-service irrigation structure on the strain distribution. The X-ray Computed Tomography (CT) technique is employed to investigate the internal concrete matrix and evaluate the defect distribution in it. The cracking system in a concrete matrix is detected as a damage type caused by the severe environment, and it is varied by the different degrees in all samples. The geometric properties of defects and their spatial location are obtained by image processing of CT images. The compression test with Acoustic Emission (AE) and Digital Image Correlation (DIC) measurements is conducted to analyze the fracture processes and acquire the damage spatial information. The AE signal descriptors are effective parameters for real-time detection and potential local damage monitoring. Moreover, the analysis of the DICM strain and displacement fields reveals the most potential fracture zones. The AE source location analysis indicated a connection between pre-existing defects and strain localization. The AE events and strain are high in the defect areas. Additionally, the amplitude and frequency of the AE events correlated with the location of the defects indicating that the structure weakness at that point leads to concentrated deformation development.</jats:p>

    <jats:p>Steel sheet pile materials are primarily used for canal structure construction for irrigation and drainage of agricultural fields in Japan. Recently, accelerated corrosion of steel materials and buckling phenomena in pitting corrosion parts have been detected in in-service steel sheet pile canals. In this study, we focus on the buckling phenomenon of in-service steel sheet pile canals, which is detected by non-contact monitoring using digital image analysis. The buckling phenomenon index is evaluated as the inclination angle of the steel sheet pile due to deformation. As a digital image analysis, Hough transform is applied, which is a figure detection method in digital images, to detect a straight line that describes the distance and angle parameters. The angle parameter corresponds to the inclination angle index of in-service steel sheet pile with a buckling phenomenon. As a result, the maximum difference between the analyzed angles by Hough transform and the measured angles is evaluated as 0.9° after the image rotation correction. The relation of the analyzed angles by Hough transform and the measured angles of the buckling phenomenon is correlated. Therefore, the degradation of steel sheet pile canals is quantitatively evaluated by using digital image analysis with unmanned aerial vehicle monitoring. This study’s significance is non-contact and simple measurement by using a digital image which can reduce a working time and perform quick diagnosis in extensive areas.</jats:p>

    <jats:p>The durability of concrete irrigation infrastructures decreases easily due to environmental effects, such as the freeze-thawed process. The degree of damage in concrete is, in most cases, evaluated by an unconfined compression test or ultrasonic test. The limiting states of structures are the result of a gradual accumulation of microdefects during the in-service period, which leads to the initiation and development of macroscopic cracks, loss of performance, and Failure. Therefore, to maintain such structures, it is necessary to properly determine the degree of damage by non-destructive testing. For effective maintenance and management of in-service structures, it is necessary to evaluate not only such mechanical properties as strength but also the degree of damage. Quantitative damage evaluation of concrete is proposed by applying the X-ray CT method and related non-destructive inspection, which is based on estimating cracking damage effects. In this study, the damage evaluation of concrete-core samples is investigated by X-ray CT parameters and the non-destructive parameters. The samples tested were taken from the damaged concrete headwork in Niigata, Japan, about 50 years after its construction. The geometric properties of the concrete matrix were calculated by the analysis of X-ray CT images. After X-ray CT measurement, an ultrasonic test and a resonant frequency test were performed. The dynamic modulus of elasticity was calculated by using ultrasonic pulse velocity and resonant frequency. As a result, based on the relationship between the geometric properties of the concrete matrix and the non-destructive parameters, the accumulation of damage in the samples tested was correlated with the ratio of the total area of cracks to the observation area. In damaged conditions, the high value of its ratio is demonstrated under low ultrasonic pulse velocity. These results suggest that the most sensitive components in a concrete body to the degree of damage are cracks in mortar and the ratio of the total area of cracks to the observation area. These values are affected by the internal actual cracks. Thus, the damage of concrete could be quantitatively evaluated by the geometric properties of the concrete matrix and its physical properties.</jats:p>

    For detailed inspections of concrete structures, non-destructive tests (NDT) are often conducted and then mechanical properties are compared with detected NDT parameters. In this chapter, damage evaluation of concrete by AE and X-ray computerized tomography (CT) tests are presented. The concrete damage is visualized by X-ray CT. Since nucleation of AE events in damaged concrete is affected by crack distribution, the damage parameter estimated is correlated with the dynamic modulus of elasticity Ed which is calculated from P-wave velocity. The results confirm that the damage of concrete could be estimated by applying AE measurement, damage parameter in damage mechanics, CT images and modulus Ed. It is also shown that the static modulus E0 is closely correlated with the dynamic modulus Ed. Based on a relation between AE rate and the damage parameter, the damage of concrete is quantitatively estimated.

    The Great East-Japan Earthquake hit Tohoku area in Japan on March 11, 2011. A large number of concrete structures were damaged due to the 9.0 magnitude earthquake of the Richter-scale. Prior to reconstruction and retrofit of these structures, damage evaluation of in situ concrete structures is now in urgent demand. In this concern, quantitative damage estimation of concrete is proposed to be performed, applying acoustic emission (AE) measurement in a uniaxial compression test of core samples. Generating behavior of AE events in the core test is quantitatively analyzed, based on the rate process theory, because notable discrepancy of AE activity is observed between damaged concrete and undamaged concrete. The damage is quantitatively defined by a scalar damage parameter in damage mechanics. Correlating AE rate with the damage parameter, quantitative estimation of damage is proposed in terms of the relative modulus of elasticity (E-0/E*). Concrete core samples were taken from reinforced concrete columns of an existing canal in the both periods of pre and post the earthquake. Prior to the compression test, distribution of microcracks in a concrete-core sample was inspected by helical X-ray computed tomography (CT), which scans at 1-mm intervals. The results suggest that the damage of concrete could be quantitatively estimated from damage parameter E-0/E* without knowing the original state of the concrete at construction. The static moduli E-0/E* and dynamic moduli E-d/E* is closely correlated. A relation between AE rate and the damage parameters is correlated, and thus the earthquake damage of concrete is quantitatively estimated using AE. (C) 2014 Elsevier Ltd. All rights reserved.

    In recent years, the accelerated corrosion of steel sheet pile in an agricultural canal has been problems. In this research, evaluation of bending characteristics is conducted in corroded steel sheet pile with concrete coating by using AE and DICM. The test specimens are made of three-layer composite which is composed of steel sheet pile, concrete and precast panel. Thus, the deformation behavior of testing samples could be evaluated by AE and DICM parameters. A relation between torsional behavior due to the concavo-convex shape of steel sheet pile and bending behavior of composite was correlated.

    For effective maintenance and management of pipeline system, it is necessary to evaluate not only the damage of pipe materials but also the detection of pressure waves such as water hammer. In this study, non-destructive inspections of pressure waves are proposed by applying acoustic emission (AE) and image analysis. Thus, pressure waves were detected in the model pipeline system, based on control of valve closing time (0.40-10.48s). The AE behavior of pressure waves were dependent on the degree of maximum pressure scale and could be evaluated applying AE parameter analysis. Using digital image correlation method (DICM), a relationship between maximum pressure level and displacement is correlated. By monitoring the pressure waves in model pipeline based on these results, the generated pressure waves was successfully detected by non-destructive inspection methods.

    For effective maintenance and management of pipeline system, it is necessary to evaluate not only the damage of pipe materials but also the detection of pressure waves such as water hammer. In this study, non-destructive inspections of pressure waves are proposed by applying acoustic emission (AE) and image analysis. Thus, pressure waves were detected in the model pipeline system, based on control of valve closing time (0.40-10.48s). The AE behavior of pressure waves were dependent on the degree of maximum pressure scale and could be evaluated applying AE parameter analysis. Using digital image correlation method (DICM), a relationship between maximum pressure level and displacement is correlated. By monitoring the pressure waves in model pipeline based on these results, the generated pressure waves was successfully detected by non-destructive inspection methods.

    As a detailed inspection of a concrete structure in service, core samples are usually drilled out and then mechanical properties are measured. In this study, damage estimation of concrete structures from core samples is developed, applying acoustic emission (AE) and X-ray computed tomography method. Concrete-core samples were taken from reinforced concrete of an existing canal. These samples are strongly damaged by freezing and thawing process. Crack distributions of concrete-core samples were inspected with helical Computerized Tomography (CT) scans, which were undertaken at 1-mm intervals. After helical CT scan, damage of testing samples was evaluated, based on fracturing behavior under compression and AE activity. AE behavior is dependent on the degree of damage, and could be approximated by applying the AE rate-process analysis and damage mechanics. AE generation behavior is associated with crack volume due to damage accumulation in concrete. The damage is quantitatively defined by a scalar damage parameter in damage mechanics. Applying the scalar damage parameter, quantitative estimation of damage is proposed in terms of relative modulus of elasticity which is named "durability index". By calculating the durability index, the initial damage of samples is estimated from AE database. The decrease in mechanical properties could be evaluated by comparing the average CT number with the durability index, both of which are affected by internal cracks generated. Thus, the damage of concrete structures is quantitatively evaluated by AE and X-ray computed tomography method. (C) 2010 Elsevier Ltd. All rights reserved.

    As a detailed inspection of a concrete structure in service, core samples are usually drilled out and then physical properties are measured. In this study, damage estimation of concrete-core samples from structural concrete is developed, applying elastic wave method and X-ray computed tomography method. Concrete-core samples taken from reinforced concrete of an existing canal were tested. These samples are strongly influenced by freezing and thawing process. The crack distributions of concrete-core samples were inspected with helical CT scans, which were undertaken at one-millimeter intervals. After helical CT scan, damage of freeze-thawed samples was evaluated, based on elastic wave parameter. It is confirmed that the development of actual cracks in core samples were decreased in CT number and elastic wave velocity. In low CT number's portion, the elastic wave parameter is decreasing compared to non-cracked portion. These results suggest that the decrease in physical properties could be evaluated by comparing average CT number with elastic wave properties in core test. These values are affected by the internal actual cracks. Thus, the damage of freeze-thawed concrete in service structures could be quantitatively evaluated by elastic wave method and X-ray computed tomography method.

    It is widely reported and realized that durability of concrete decreases due to such effects, as salt and chemical attack, freezing and thawing, and carbonation and fatigue. In existing structures mechanical damage of concrete has been practically estimated from the strength by a compression test and a rebound hammer test. For effective maintenance of concrete structures, it is necessary to evaluate quantitatively not only the strength of concrete but also the degree of damage. Quantitative damage evaluation of structural concrete is proposed by applying acoustic emission (AE) technique and damage mechanics. Consequently, damage evaluation is conducted on concrete cores of an existing structure.
    Core-samples were collected from an arch fragment of a reinforced concrete road bridge that had been in service for 87 years. Compressive strengths and Young's moduli were measured during the compression test along with AE measurement. Dynamic Young's moduli were also calculated from the longitudinal wave velocity. Thus the relative damages are quantitatively evaluated from static and dynamic Young's moduli and compared with results of AE rate-process analysis.

    In recent years, deterioration of concrete structures has been widespread and become a social problem. Because the durability of concrete structures decreases easily due to such external effects, as carbonation and freezing-thawing process, it has been important to evaluate not only the strength but also the damage of concrete. Thus, damage evaluation of structural concrete is developed, applying acoustic emission (AE) method. Damaged concrete samples are examined, based on fracturing behavior under unconfined compression. AE behavior of the concrete under compression is dependent on the degree of damage, and could be analyzed by the rate process analysis. Using Loland's model, a relationship between stress and strain is modeled, and a relation between the AE rate and the damage parameter is correlated. By calculating Young's modulus of the intact concrete from the database of this correlation, the relative damage of the concrete in an actual structure is successfully estimated.
