...Yu Zhu; Haixu Wang; Xiaojun Sun; Feng Li; Xuefei Guan; Min Huang; Jingjing He The identification of cracking damage and the dynamic diagnosis of damage evolution are of great importance to prolong the service life of asphalt mixture materials. Acoustic emission (AE) can identify the formation...

...R. Vidya Sagar; Priyan Roy T.; Tribikram Kundu This article reports the observation made during the compressive fracture process of cementitious materials, which has been studied using nonlinear ultrasonic testing (NUT) and acoustic emission (AE) testing techniques. The generated higher harmonics...

... acoustic emission waveforms. This paper presents a probabilistic deep learning approach for fatigue crack width estimation, employing an automated wavelet feature extractor and probabilistic Bayesian neural network. A dataset constituting the fatigue experiment on aluminum lap joint specimens is considered...

...Shane Ennis; Victor Giurgiutiu This article addresses the classification of fatigue crack length using artificial intelligence (AI) applied to acoustic emission (AE) signals. The AE signals were collected during fatigue testing of two specimen types. One specimen type had a 1-mm hole for crack...

... materials using NDE methods [ 12 , 16 ]. Among them and in relation to the methods used in this paper, acoustic emission (AE) has been widely used to evaluate the failure processes [ 9 , 17 – 20 ]. AE refers to the energy release in the form of transient elastic waves due to a sudden change in a material...
