Electromagnetic acoustic transducer (EMAT) is a nondestructive testing technology widely used in health monitoring. However, it is difficult to evaluate the depth of defects accurately with consideration of the ambiguous relationship between the cracks and feature values. Therefore, an accurate evaluation method for the depth of surface cracks needs to be established. In this paper, a fusion characterization method based on fuzzy relationship matrices is proposed. Firstly, the different depth estimated values of the surface crack are obtained based on the relationship modals between the crack depth and multiple different feature values. Secondly, a difference matrix is established that can describe the difference in accuracy between different depth estimated values, and a relationship matrix is constructed based on the triangular fuzzy number method for evaluating the quantization accuracy. Thirdly, the weights of different estimated values in the fusion quantification were determined, and the final defect depth was obtained. Finally, we applied our approach to experimental data and its maximum quantization relative error was 5.9%, which demonstrates its capability to characterize surface cracks compared with other methods.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 1","pages":"S19 - S36"},"PeriodicalIF":0.9,"publicationDate":"2026-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An integrated experimental framework combining hydrostatic pressure testing and ultrasonic detection was developed to replicate in-service damage evolution. Online monitoring captured continuous nonlinear ultrasonic responses during accelerated damage, while offline measurements provided discrete validation points across progressive damage stages. The methodology employs pulse-echo methods with third-harmonic analysis to quantify acoustic nonlinearity parameters at critical deformation sites. Results demonstrate that nonlinear ultrasonic parameters exhibit sensitivity to microstructural degradation during plastic deformation. A characteristic peak phenomenon consistently emerges in the nonlinearity evolution curve at a critical damage threshold, serving as a reliable precursor to failure. Offline measurements using pulse-echo and V-scan methods corroborate online findings, confirming measurement reproducibility. Furthermore, impact strength testing establishes a correlation between acoustic nonlinearity parameters and material degradation. This work establishes nonlinear ultrasonics as a viable methodology for real-time structural health monitoring of PE pipes. The nonlinear ultrasonic technology bridges microscopic damage progression with macroscopic mechanical behavior, enabling early detection of ductile damage before macroscopic failure occurs. The findings provide a foundation for developing condition-based assessment protocols in pipe integrity management.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 12","pages":"1446 - 1457"},"PeriodicalIF":0.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, during magnetization, a local area of the plate was subjected to a variable magnetic field using a flat coil placed between the poles of the AEM. The measuring coil, located on the same frame as the bias coil, was in contact with the plate surface. Magnetic property measurements were taken from both sides of the plate in its central part. It was established that the curves measured with the AEM installed on the top and bottom of the deformed plate differ significantly. On the curves measured from the top side of the plate, where the surface experiences maximum compressive stresses, one central peak in the region of the coercive force and two additional infections (peaks) on both sides of it are observed. On the curves measured from the tension side of the plate, additional infections were observed only at low frequencies of the bias field, when the signal from the measuring coil also contained information about the compressed layers of the plates. The fields at which the inflections occur depend both on the applied load (magnitude of stresses) and on the frequency of the bias field generated by the primary transducer coil. The dependence of the average field of the peaks on the load applied to the plate is close to linear.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 12","pages":"1469 - 1476"},"PeriodicalIF":0.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure complete crack repair, it is often necessary to expand the repair area, resulting in a larger range of anti-corrosion coating polished. Therefore, it is crucial to introduce a new method that can accurately reconstruct the shape of branched cracks. This paper focuses on the key issues in reconstructing the shape of branched cracks and uses simulation and experimental methods to study the magnetic field distribution of these cracks. The magnetic field image generated by the crack is analyzed using image processing techniques, and the feature points of the image are extracted. The method of graph theory is introduced to research the reconstruction rules of branched cracks, and the method of automatic reconstruction for the surface shape of cracks is further studied. Additionally, this method is robust and achieves satisfactory reconstruction results even when missing data leads to low-resolution images. The experimental results show that the proposed method can achieve shape reconstruction of branched cracks with an error of 0.3–7.3% in branch crack length and 1.8–7.4% in branch crack angle. This method can reduce damage caused by excessive polish and provide the possibility for precise maintenance.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 12","pages":"1488 - 1503"},"PeriodicalIF":0.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, during the process of long-term service, crack damage is inevitable. In response to this problem, this article presents a crack damage imaging and localization method based on Lamb waves. This method, by analyzing the propagation characteristics of Lamb waves before and after damage, proposes a novel damage indicator—the crack damage factor (CDF)—for the visual visualization characterization of cracks. The research approach was validated through experiments. Initially, a sensor array was configured to form a relatively dense detection network, and then the guided wave signals of the stiffened plate both before and after damage were acquired, the CDF was computed. Subsequently, the initial imaging of the damaged area was accomplished by the reconstruction algorithm for probabilistic inspection of damage (RAPID). On this foundation, to rectify the CDF of the crack parallel path, a method of grouping refinement was put forward. Finally, the corrected CDF and the CDF values of other paths were utilized in RAPID to realize the imaging and localization of the crack damage. The experimental outcomes demonstrate that this approach visualizes and localizes the cracks in stiffened plates accurately and efficiently, validating its feasibility and efficacy in practical applications. It offers a novel solution for damage detection and crack imaging of stiffened plate structures.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 12","pages":"1430 - 1445"},"PeriodicalIF":0.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147588534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, a bimodal detection function is constructed to locate the extreme points of the histogram, and the optimal threshold is dynamically calculated to realize the binarization of the damaged area, while fully retaining weak defect details and mitigating edge blurring.
