- W2520119694 abstract "Acoustic emission analysis (AEA) has become a promising method to monitor the change in the condition of concrete structures. The research project aims at investigating the influence of reinforcement and cracks on wave propagation. Therefore, localisation algorithms using heterogeneous velocity models are developed. Taking the heterogeneity of concrete and the influence of reinforcement into account will improve the source localisation accuracy. Until now it is common to use homogeneous velocity models to localize the acoustic emission (AE) source. As a consequence effects of heterogeneity, especially reinforcements, and cracks cannot be considered. Therefore, a new numerical reinforced concrete model (NRCM) is developed which is used to investigate the influence of reinforcements and cracks on the wave propagation path and their influence on the signal recorded by piezoelectric sensors. As a rule the reinforcement layout is known. Other wise, the layout can be determined using acoustic tomography for example. The only information provided by the velocity model of the specimen is the wave velocity of each voxel depending on the assigned material. A localization method is modified for processing these heterogeneous velocity models. The source location is calculated iteratively. The difference between the calculated signal arrival time and the measured arrival time is used to update the estimated source location and time. It is common to use one homogeneous wave velocity, the distance between the estimated source location and a sensor as well as the estimated source time, to compute the calculated arrival time. Using the heterogeneous velocity model, the wave travel time between the estimated source location and a sensor can be calculated as sum of the wave travel times through every voxel assuming a linear wave propagation path. An acoustic tomogram could be updated using the data recorded by the sensors monitoring the specimen. Hence, also the velocity model could be updated. Cracks could be considered in the velocity model, even if they occur after the preliminary tomography. The combination of three dimensional acoustic tomography with AE analysis is a novel and promising approach." @default.
