Acoustic Emission Source Identification in Large Scale Fibre Reinforced Composites
Within the last decades many approaches have been proposed to perform source identification in fibre reinforced composites. Some of them have been validated using skilled micromechanical experiments or by using reference specimens in combination with imaging methods, leaving strong evidence that these approaches are valid tools to perform source identification tasks. Lately, also numerical meth...
متن کاملIdentification of the Acoustic Emission source during a comparative study on diagnosis of a spur gearbox
Condition monitoring of gears with vibration analysis is well established whilst the application of Acoustic Emission (AE) to gear defect diagnosis and monitoring is still in its infancy. This paper details results of an experimental programme to ascertain and validate the applicability of AE to seeded gear defect identification. Furthermore, comparisons are made to vibration diagnosis. As a di...
متن کاملLocalization of Acoustic Emission Source Based on Chaotic Neural Networks
Because of containing several model waveforms and transmission speed of each model are various, the source signal of rub-impact acoustic emission (AE) will lead to waveform distortion in propagation process, and it is difficult to achieve exact source location by traditional time difference of arrival algorithm. A chaotic neural network technique was introduced to calculate the location of AE s...
متن کاملIdentification of Liquid Boiling by Acoustic Emission
− Comparisons of the acoustic emission signals from the pool and microlayer boiling and water drop evaporation are the aim of the paper. The main relationships, dependences and research results will be presented. The mechanism of acoustic emission generation in liquid boiling and evaporation is discussed. Based on a theoretical analysis, a set of random process characteristics in time and frequ...
متن کاملDamage Source Identification of Reinforced Concrete Structure Using Acoustic Emission Technique
Acoustic emission (AE) technique is one of the nondestructive evaluation (NDE) techniques that have been considered as the prime candidate for structural health and damage monitoring in loaded structures. This technique was employed for investigation process of damage in reinforced concrete (RC) frame specimens. A number of reinforced concrete RC frames were tested under loading cycle and were ...
