Acoustic emission for characterization of failure mechanisms in textile reinforced mortar laminates under tensile loading Vrije Universiteit Brussel
AE parameters and indices to the different fracture mechanisms that are successively activated during the failure process of the complex TRC composite material. These mechanisms include multiple matrix ...

Effect of fiber surface conditioning on the acoustic emission behavior of steel fiber reinforced concrete Vrije Universiteit Brussel
The role of coating in preserving the bonding between steel fibers and concrete is investigated in this paper. Straight types of fibers with and without chemical coating are used in steel fiber reinforced concrete mixes. The specimens are tested in bending with concurrent monitoring of their acoustic emission activity throughout the failure process using two broadband sensors. The different stages of fracture (before, during and after main ...
Multiaxial damage identification of angle-ply laminates using acoustic emission and other online monitoring techniques Vrije Universiteit Brussel
The aim of this research is the combined use of acoustic emission with other online monitoring techniques in order to identify the damage sequence of carbon fiber reinforced epoxies. Initially, common lay-ups were tested and their acoustic emission was monitored and analyzed with respect to the developing damage, in order to identify basic damage modes. Following this, angle-ply laminates were tested to characterize the damage evolution under ...
Monitoring of failure of composite laminates using acoustic emission Vrije Universiteit Brussel
Acoustic emission (AE) is suitable for monitoring the evolution of degradation in structural components as well as for localizing damage. In the present study acoustic emission is employed for the location and identi fi cation of the service induced damage in cross ply laminates. The sequence of the different failure mechanisms, i.e. transverse matrix cracking and the subsequent delamina-tion propagation at the 0°/90° interface is followed ...
Monitoring the fracture behavior in ceramic matrix composites by infrared thermography and acoustic emission Vrije Universiteit Brussel
Improvement of a new acoustic emission analysis technique to determine the activated carbon saturation level: A comparative study Universiteit Hasselt
The Influence of Sensor Size on Acoustic Emission Waveforms-A Numerical Study Vrije Universiteit Brussel
The performance of Acoustic Emission technique is governed by the measuring efficiency of the piezoelectric sensors usually mounted on the structure surface. In the case of damage of bulk materials or plates, the sensors receive the acoustic waveforms of which the frequency and shape are correlated to the damage mode. This numerical study measures the waveforms received by point, medium and large size sensors and evaluates the effect of ...
