Abstract
This study presents a novel approach for characterizing crack propagation in lightly reinforced concrete beams using acoustic emission techniques. The primary focus remains to simulate the mode I crack path, estimate the crack length, and to generate 3D crack profiles. Lightly reinforced concrete beams were designed according to Bosco and Carpinteri's minimum reinforcement criteria and tested under centre-point CMOD control flexure testing. An unsupervised Gaussian Mixture Model clustering technique was employed to categorize acoustic emission events into distinct clusters based on their average frequency and rise angle. This approach enabled the selection of highly probable mode I acoustic emission events based on their posterior probability. A spatial binning method was applied to the filtered tensile crack events to simulate the crack path and 3D crack profile for the lightly reinforced beam specimen. The study also incorporated a temporal binning strategy to predict the crack length. A monotonic constraint was applied to the filtered events, balancing noise reduction and sensitivity in detecting crack length. The prediction of the crack growth was subsequently compared with the results of the digital image correlation. This research demonstrates the effectiveness of acoustic emission in simulating real-time crack attributes in reinforced concrete structures.
期刊介绍:
Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense.
Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems.
Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
