Probability density field of acoustic emission events: Damage identification in concrete structures
Highlights A newly proposed method estimates the probability density of the location of AE events. This method has been applied in a shear test of a full-scale reinforced concrete beam. The results show that the new method can more clearly identify the crack patterns in concrete structures. The probability density of AE events is found related to local crack widths.
Abstract This paper proposes a new damage identification method, namely, the probability density field of acoustic emission (AE) events. This new method provides a different perspective to deal with the uncertainties in the source localization process. We treat the source location as a random variable, and estimate its probability density field based on a probability density function. The function was found from simulations where various uncertainties were included. The probability of AE events falling in a certain space range is the integral of the probability densities over that range. We apply the new method in a failure test of a full-scale reinforced concrete beam. The resultant probability density field clearly reflects the crack patterns of the specimen and a close relationship with the crack width.
