Damage classification in reinforced concrete beam by acoustic emission signal analysis

摘要: Acoustic Emission (AE) is a non-destructive testing technique which can be used to identify both the damage level and nature of that such as tensile cracks shear movements at critical zones within structure. In this work, acoustic emission parameters amplitude, rise time, average frequency signal strength were classify determine level. Laboratory experiments performed on beam (150 × 250 1900 mm). The analysis was successfully crack levels in accordance with observations made during an increasing loading cycle.
