Abstract:
Acoustic Emission (AE) sensing is used in the field for the testing of metal, composite and structures, as non-destructive techniques. The AE technique allows determining the size of the cracks, damages, fractures and failures into materials. Possible causes of the internal-structure changes are crack initiation and growth, crack opening and closure, dislocation movement, twinning, and phase transformation in monolithic materials and fibre breakage and fibre-matrix debonding in composites. AE technology involves the use of ultrasonic transducers to listen for the sounds of failure occurring in materials and structures. Monitoring the stability of construction structures, by AE techniques get involve detecting the onset and evolution of stress-induced cracks and preventing the structural failures.
