“…According to [14], the verification of the validity of the plotted POD curve can be checked by the comparison between the observed a 50 value and the threshold value âth . In fact, when we have the same results as what we see in this study, it can be concluded that the plotted POD curve is correct.…”

“…Particularly, ultrasonic inspection technique has shown great capacities for crack detection, analysis and prediction in SHM [9][10][11][12][13][14][15]. This method provides an opportunity to detect material discontinuities and obtain information allowing the fatigue life prediction and risk management.…”

Fatigue crack propagation can considerably reduce the life of components, leading to sudden failures. This paper provides a method for fatigue life prediction based on ultrasonic non-destructive inspection applied on Al 2024 T3 material.A new crack quantification model based on ultrasonic waves features is developed. To analyse the performance and efficacity of the model, the probability of detection is determined using the "signal response" technique.The Paris model is used to predict the fatigue life taking into consideration the initial crack distributions, the dispersion of the parameters underlined by the Least-squares method and Monte-Carlo simulations.Reliability evaluation is discussed later for two cases: Detection and No-detection case.If no indication is presented, an inspection detection threshold is determined and optimized. This proposed indicator will be helpful for industrial environments whenever the inspection machine does not have any indication.Considering the ultrasonic inspection data, an updating reliability via the Bayesian approach is suggested. The results of this approach can lead to a gain in the life span or a gain of the costs generated by the failure of the part.

The way a wave behaves, while propagating across a medium, varies with the wave type and the medium. So, knowledge of the behaviour of a wave in a system with a different form of damage, and behaviour of different types of waves in a particular system is an essential prerequisite for almost all activities in structural system identification and mainly for damage detection and localization of damage. This paper presents a comparative study of various wave propagations, that has been done by researchers in various structural systems. Further, a numerical model of an isotropic plate using finite element is created both with and without damage. The behaviour of waves has been studied. Finally, the comparative result is shown. This paper offers a new perspective for ongoing research by providing the most recent developments, difficulties, and prospects of wave propagation behaviours for damage detection and localization in the commonly used structural systems and structural elements. While propagating through different structural systems and components, the most used waves, which are (a) Shear wave, (b) Rayleigh wave, (c) Ultrasonic wave and (d) Lamb wave, have been thoroughly investigated. Along with several difficult problems for future growth, the summarized observations are provided.
