Damage classification in reinforced concrete beam by acoustic emission signal analysis [PDF]

, 2013
Acoustic Emission (AE) is a non-destructive testing technique which can be used to identify both the damage level and the nature of that damage such as tensile cracks and shear movements at critical zones within a structure.
