Acoustic emission for fatigue damage characterization in metal plates

Damage Assessment in Fibrous Composites Using Acoustic Emission

“…2 . This has been shown in a number of studies concerning different kinds of materials like rock (Shiotani 2006), concrete (Ohno and Ohtsu 2010, Soulioti et al 2009, Aggelis et al 2011a, metals (Aggelis et al 2011b) and composite laminates (Aggelis et al 2010b). It originates from the different elastic wave modes (longitudinal and shear) that are emitted from the mode I excitation (opposing movement of the crack faces) and mode II (sliding movement) respectively (Aggelis et al 2010c).…”

Deformation Characteristics of Aluminium Composites for Structural Applications

“…Nondestructive evaluation techniques are powerful tools for monitoring damage in composite materials [24]. Infrared thermography was used to monitor the plane crack propagation behaviour of particulate-reinforced AMCs [25,26].…”

Prediction of quasi-static delamination onset and growth in laminated composites by acoustic emission

“…AE have been utilized by some researchers to study the crack growth in homogeneous metallic materials such as Aluminum and Steel [10][11][12][13][14][15]. Yu et al [16,17] Therefore the investigations of crack onset and growth by AE method have been lacking in literature, primarily because of difficulties in eliminating extraneous background noise and separation of AE signals obtained from different damage sources.…”
