Abstract
Acoustic emission (AE) is microseismic signal generated by microcracks in brittle
material such as concrete or rock. AE signals carry information about the source,
including location and magnitude. Therefore, it is useful tool in evaluating deterioration of a structure. The growth of damage and potential failure can be identified by monitoring AE. It was observed that AE rate increased during the peak. Besides, detailed analysis showed that the locations of AE events coincide with the location of damage. The experimental results also showed damaged material had higher AE rate than “healthy” material.
