Özet
Acoustic emission (AE) method has been widely used for investigating damage in materials and structures. It allows monitoring the damage progress within the material during loading. In conventional parameter-based AE analysis, only AE parameters are recorded and analyzed to clarify fracture behavior in materials. Quantitative analysis methods allow for a comprehensive fracture characterization of materials in which waveform itself is stored and analyzed. Large number of research and case studies reveal that for civil infrastructure monitoring, parameter-based analyses of AE are preferred compared with quantitative analyses. This is because, concrete, being mostly used material for constructing civil structures, has a very complex nature and without proper and adequate instrumentation, set-up and algorithms, it is difficult to properly characterize fracture mechanisms with quantitative techniques. Still, it is very important to obtain these fracture characteristics such as the time crack developed, the location of the crack and also the type of the crack to better understand the fracture behavior of a structural element under consideration such as how this element behaves under certain load levels and what leads to its failure. There have been numerous challenges and solutions in application of quantitative AE techniques to civil infrastructure from reliable AE source localization to defect type identification. In this study, these applications and solution methods have been reviewed thoroughly and presented. © 2021 International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII.
