Abstract

Acoustic emission (AE) is a favourable technique for crack detection in concrete structures. One main objective of AE is to estimate the origin of the source which is called source localization. The spatial distribution of the estimated source locations indicates the cracking location. To perform an effective source localization, a proper design of sensor layout is an important basis. An unjustified sensor layout may lead to larger localization errors or missing of AE events. Many studies in literature apply AE source localization but do not provide a rational explanation of the design of sensor layouts. This paper presents a comprehensive procedure for designing a sensor layout, including determination of measuring zone, establishment of sensor spacing and design of sensor placement. The provided method is demonstrated in an experiment that involves AE monitoring of failure of a full-scale reinforced concrete beam. We use the experiment to further study the influence of the sensor layout. The results of this paper suggest several criteria to guide the design of sensor layouts for source localization.
