Journal ArticleDOI
Damage classification in reinforced concrete beam by acoustic emission signal analysis
Shahiron Shahidan,Shahiron Shahidan,Rhys Pulin,Norazura Muhamad Bunnori,Karen Margaret Holford +4 more
TL;DR: In this article, the acoustic emission parameters of amplitude, rise time, average frequency and signal strength were used to classify the damage and to determine the damage level in a beam with an increasing loading cycle.
Journal ArticleDOI
Acoustic emission signal for fatigue crack classification on reinforced concrete beam
TL;DR: In this article, Acoustic emission (AE) signals were analyzed to identify the classes of reinforced concrete (RC) beam corresponding to a specific crack mode and the relationship between average frequency and RA value indicated clear trend with respect to crack classifications.
Journal ArticleDOI
Diagnostic of fatigue damage severity on reinforced concrete beam using acoustic emission technique
Noorsuhada Md Nor,Azmi Ibrahim,Norazura Muhamad Bunnori,Hamidah Mohd Saman,Soffian Noor Mat Saliah,Shahiron Shahidan +5 more
TL;DR: In this paper, diagnostic of fatigue damage in reinforced concrete (RC) beams using acoustic emission (AE) technique was investigated based on severity analysis of AE signal strength during service life of the beams, bath-tub curves derived from AE signal are presented and divided into three stages; burn-in, steady state and burnout.
Journal ArticleDOI
Characteristics of Treated Palm Oil Fuel Ash and its Effects on Properties of High Strength Concrete
Abdullah M. Zeyad,Megat Azmi Megat Johari,Norazura Muhamad Bunnori,Kamar Shah Ariffin,Nurdeen M. Altwair +4 more
TL;DR: In this article, the ultrafine palm oil fuel ash was used to produce high strength concrete by replacing the ordinary Portland cement at 0, 20, 40 and 60% on a mass-for-mass basis.
Journal ArticleDOI
The use of acoustic emission for the early detection of cracking in concrete structures
TL;DR: In this article, the authors relate the acoustic emission obtained from reinforced concrete beams to the onset of cracking of these beams subjected to the four-point bending test and demonstrate that areas of damage owing to cracking can be clearly identified by acoustic emission source location.
