“…Hence, the name of method was altered and the IADP (Identification of Active Damage Processes) name was proposed. The classes adopted in the reference signal database for reinforced concrete structures [14] Table 1. Tests carried out on statically determinate and indeterminate beams demonstrate that Classes 6, 7 and 8 occur just before failure, and almost simultaneously.…”

“…The method based on the measurement and analysis of acoustic emission (AE) signals generated by active destructive processes caused by the loading action in the examined member, or in the whole structure, could be most obviously classified as NDT. The analysis of identification and location of destructive processes provides a basis for the diagnostics of the examined structures [4][5][6][7][8][9][10][11][12][13][14]. The obvious advantage offered by the method is the possibility of conducting measurements of the whole structure of concern (e.g.…”

Abstract. The study presents the analysis of the process of crack formation and crack width growth in statically determinate and hyperstatic reinforced concrete beams with the IADP acoustic emission method. The beams were subjected to the monotonic, variable with unloading, and variable cyclic loading schemes. The criteria of structural damage were established to account for the structure durability.

“…One of the factors that determine the durability of the material is the occurrence of crack initiation on the material performance and the advanced process provides a warning that the condition of the material has been threatened (Goszczyńska, 2014). Sangid (2013) studied the importance of crack initiation in predicting the fatigue life of components.…”

A statistical distribution for crack growth technique is one of the important issues emerging from the fatigue crack propagation process. This study aims to compare three different statistical distributions for providing the best modelling of the fatigue data. The normal, the lognormal and the Weibull distribution are compared for determining a better fit for the variables. Kolmogorov-Smirnov has been chosen as the criterion of the best distribution of the variables. Ten replicate specimens of aluminium alloy A7075-T6 in constant amplitude crack tests were conducted. The number of cycles for the formation of the initial crack and initial crack length were taken as random variables. A Bootstrap approach was applied for ensuring that the chosen distribution was the best representative for this type of variables since small data was incorporated in this analysis, it was not suitable to justify the true population. Thus, the result showed that the lognormal distribution was the best distribution to represent the number of cycles and the length of the initial crack. It was found that whether the normal and lognormal types were suitable for those variables, the lognormal was more conservative for these types of variables. These two variables played the main role in life prediction. Therefore, an analysis of the statistical distribution is highly important. It is believed that these results lead to the significant prediction of fatigue lifetime.
