Monitoring fracture of steel corroded reinforced concrete members under flexure by acoustic emission technique Vrije Universiteit Brussel
Acoustic emission (AE) technique is used for monitoring and evaluating the influence of corrosion on the structural behaviour of steel reinforced concrete (RC) beams under three-point flexure test. In this study, steel corrosion was accelerated by electro-chemical method utilising a direct current (DC) power supply and 5% sodium chloride (NaCl) solution. The steel corrosion that was induced into beam specimens casting were estimated at 0%, ...
Improved crack monitoring in structural concrete by combined acoustic emission and digital image correlation techniques Vrije Universiteit Brussel
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
Acoustic emission for fatigue damage monitoring in cross-welded aluminum plates Vrije Universiteit Brussel
Acoustic emission monitoring of crack propagation in additively manufactured and conventional titanium components Vrije Universiteit Brussel
Additive manufacturing (AM) is a novel and innovative production technology that can produce complex and lightweight engineering products. In AM components, as in all engineering materials, fatigue is considered as one of the principle causes of unexpected failure. In order to detect, localise and characterise cracks in various material components and metals, acoustic emission (AE) is used as a non-destructive monitoring technique. One of the ...
Monitoring the hydration of cementitious material by acoustic emission Vrije Universiteit Brussel
Studying the mechanisms affecting the very early age hydration as well as the microstructure of cementitious materials is essential to improve concrete performance. Consequently, it is ncccssary to monitor and understand the early age hydration process. In this work, continuous acoustic emission (AE), ultrasonic pulse velocity (UPV), and capillary pressure monitoring has been applied on consolidated and non-consolidated cement paste to study ...
Monitoring of autonomous healing process of concrete by acoustic emission and digital image correlation Vrije Universiteit Brussel
In this study, cracking formation and repair due to autonomous healing of concrete beams, tested in two stages of bending (loading-reloading) are reviewed. Encapsulated PU-based healing agent is embedded into concrete beams and is released when crack formation triggers and actuates the chemical repair process. The released agent fills the open crack and seals the fractured area. The potential mechanical recovery of the damage is investigated. ...
