Damage Evaluation Methods Of Structural Members Using Acoustic Emission (Ae) Technique
Acoustic emission (AE) is an important nondestructive evaluation (NDE) technique used in the field of structural engineering for both case local and global monitoring. This technique was employed to investigate the process of fracture formation in reinforced concrete and steel structures. In main ob...
