“…Te crack is made by cutting the pipeline. In order to ensure the consistency of the damage degree, the cracks on the main pipe and branch pipe were cut along the circumference of 1/3, as shown in Figures 6(a)-6(c) [21], and the locations were selected at the typical locations of fatigue cracks: (1) the bend of the main pipe, (2) the joint of the mass block pipe and large pipe, and (3) the connection between the vertical bend and the big pipe. For the lossless pipeline models included, a total of 4 test models were obtained, as shown in Table 1.…”

To study vibration fatigue damage localization of offshore oil and gas pipelines, aiming at the location error caused by uncertainty of the initial parameters in backpropagation (BP) neural network training, an improved BP neural network based on the genetic algorithm (GA) is proposed to locate pipeline damage. This approach was verified by experiments and simulations. First, a BP neural network for structural damage location was constructed, and a method to optimize the BP neural network parameters based on the GA was established. Then, a finite element model was established based on the measured data from modal tests of a physical pipeline model, and a large number of vibration neural network training samples were obtained using the finite element model. Finally, to show that the improved BP neural network based on the GA had a better damage location accuracy, the location results of the original BP and GA BP methods were compared for cases with no noise and with 5% noise. The results show that the average error of the BP neural network based on the GA was less than 3%, which was 11.6% lower than that of the original BP neural network.

Real life logical rule is not always satisfiable in nature due to the redundant variable that represents the logical formulation. Thus, the intelligence system must be optimally governed to ensure the system can behave according to non-satisfiable structure that finds practical applications particularly in knowledge discovery tasks. In this paper, we a propose non-satisfiability logical rule that combines two sub-logical rules, namely Maximum 2 Satisfiability and Random 2 Satisfiability, that play a vital role in creating explainable artificial intelligence. Interestingly, the combination will result in the negative logical outcome where the cost function of the proposed logic is always more than zero. The proposed logical rule is implemented into Discrete Hopfield Neural Network by computing the cost function associated with each variable in Random 2 Satisfiability. Since the proposed logical rule is difficult to be optimized during training phase of DHNN, Election Algorithm is implemented to find consistent interpretation that minimizes the cost function of the proposed logical rule. Election Algorithm has become the most popular optimization metaheuristic technique for resolving constraint optimization problems. The fundamental concepts of Election Algorithm are taken from socio-political phenomena which use new and efficient processes to produce the best outcome. The behavior of Random Maximum 2 Satisfiability in Discrete Hopfield Neural Network is investigated based on several performance metrics. The performance is compared between existing conventional methods with Genetic Algorithm and Election Algorithm. The results demonstrate that the proposed Random Maximum 2 Satisfiability can become the symbolic instruction in Discrete Hopfield Neural Network where Election Algorithm has performed as an effective training process of Discrete Hopfield Neural Network compared to Genetic Algorithm and Exhaustive Search.

In this paper, a damage signal recognition for carbon fiber composites based on modal acoustic emission is proposed, which can realize the damage classification of acoustic emission signals. First, according to modal analysis results of the acoustic source signal obtained from the pencil lead breakage experiment, digital filters are designed to realize the mode separation of symmetric (S0) and anti‐symmetric (A0) in the acoustic emission signal. Based on the modal characteristics of the damage signals, an algorithm for the recognition of damage signals is established. The accuracy of damage signal recognition in pure matrix cracking and fiber breakage is 97.9% and 96.2%, respectively. Then, the algorithm is used to identify the damage signal during the indentation experiment of the carbon fiber composite laminates and analyze the damage evolution process. Finally, using the machine learning method to locate the damage location during the indentation experiment, the error between the predicted acoustic emission source and the actual results is less than 2.8%. In this study, the classification of damage modes and the location of damaged sound sources during the indentation experiment of carbon fiber composite laminates were realized, which provided a reference for structural health monitoring of composite materials.Highlights AE technique is used to study the indentation damage of CFRP laminates. An algorithm for damage signal recognition based on MAE is proposed. Prediction of damaged location by combining AE and machine learning. Effectively realizes damage signal classification and location prediction.
