The application of CF or DMAS technologies in various combinations is promising, as these technologies are relatively simple, require minimal additional computational resources, and can be applied to echo signals measured by conventional flaw detectors operating with antenna arrays. Numerical and model experiments have demonstrated that the use of these methods allows for an increase in the resolution of the images of reflectors by more than two times and a reduction in noise level by more than 20 dB. In a numerical experiment, it was shown that phase distortions due to complex coefficients of refraction and reflection can cause the indication of the crack tip to shift from its true position by approximately one wavelength, even with precisely known experimental parameters when operating on a straight beam on a transverse wave. This represents a significant error for flaw detection tasks. However, if phase correction is applied during the reconstruction of the images of reflectors, then the indication of the crack tip aligns with its actual position. CF and DMAS technologies have demonstrated their effectiveness even when working with noisy echo signals.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 12","pages":"1335 - 1349"},"PeriodicalIF":0.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455502","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}

The main factors influencing the error in determining the coordinates of AE sources in planar location using the standard method are considered. These include the threshold method for determining the moment of signal registration by AE transducers based on the rising wavefront exceeding the discrimination threshold (left( {{{u}_{{{text{th}}}}}} right)), the signal sampling frequency level (left( {{{f}_{d}}} right)), and the influence of the dispersion properties of the medium on the attenuation of pulse amplitude and the speed of propagation. To reduce the impact of the factors listed above on the results of the coordinate location of AE sources, a new method is proposed, based on the use of correlation dependences of the AE pulse propagation speed in relation to the amplitude of the recorded signals and accounting for the delay in the moment of pulse recording by AE transducers in the threshold detection method. A series of preliminary tests were carried out to implement the proposed method during which AE pulses with a maximum amplitude level of ({{u}_{m}}) = 45–90 dB were generated using an electronic simulator. The position of the AE pulse emission source varied in the range from 150 to 700 mm relative to the receiving transducers of the antenna array. As a result of applying the developed method, the probability of detecting AE sources increased to (p = 0.71), whereas with the standard approach it did not exceed (p = 0.36).","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 12","pages":"1325 - 1334"},"PeriodicalIF":0.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455571","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}

It can be used to assess homogeneity, uniformity, integrity and stress state of a concrete. The latter is dependent on a phenomenon called acoustoelastic effect which relates stress state of a material to pulse velocity, however apart from pulse velocity, amplitude of the waves is highly stress dependent. This research paper presents an experimental study to quantify change in ultrasonic wave amplitude when concrete element is subjected to stress and propose a novel relationship between amplitude and stress. Experiments were conducted on cylindrical concrete specimens subjected to uniaxial loading and changes in ultrasonic wave velocity and amplitudes were observed. The study concluded that amplitude holds greater potential in determination of stress state and may be used as a primary tool for the same. Velocity exhibited linear increase with applied stress, an average change of approximately 4%. Conversely, the amplitude of an ultrasonic pulse increased linearly by more than 120% under stress. As the system approached failure, there were rapid fluctuations in amplitude, which could be interpreted as an early indicator of impending failure.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 12","pages":"1376 - 1386"},"PeriodicalIF":0.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455637","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}

The prediction and evaluation of mechanical properties in composite structures are highly complex due to the intrinsic diversity and structural intricacies of composites, further complicated by the nature of the loads they experience. Therefore, the analysis of the buckling modes of composite stiffened panels with openings constitutes a significant challenge in engineering applications. This paper presents a study investigating the combined effects of compression and shear loading on a typical open-hole composite T-stiffened panel. The testing procedure was monitored utilizing digital image correlation (DIC) and strain gauge measurement techniques. The results indicate that stress concentration occurred at the opening in the skin, with material damage initiating in the stress concentration zone adjacent to the opening. Local buckling manifests in the skin, characterized by interval-distributed convex or concave regions. Additionally, high-fidelity numerical simulation approaches were used to further validate the accuracy of the DIC technique, and the results of both showed excellent consistency. DIC technology proves to be both effective and efficient in measuring strain fields and out-of-plane displacement fields, as well as in determining the initiation points of failure surrounding circular cutouts under combined compression and shear loading.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 12","pages":"1420 - 1433"},"PeriodicalIF":0.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455568","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}

The load factor for various cross sections of the pipeline was calculated. Graphs of the dependences of the magnetic characteristics averaged over the cross section on the load factor were constructed. It was found that the cross sections most critical for failure, where the load factor exceeds the critical value of 1.2, corresponded to reduced values of coercive force and residual magnetic induction measured along the pipeline axis. It was shown that measurements along the axis at the upper part of the pipeline, i.e., at the 12 o’clock position, exhibit a similar dependence to the values averaged over the cross section, indicating that for pipeline aerial crossings, measurements at the 12 o’clock position alone may be sufficient.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 12","pages":"1396 - 1406"},"PeriodicalIF":0.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455638","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}

Agglomeration of nanoparticles refers to a harmful defect over the nanocomposite materials, affecting the final performance of the material. The present study focuses on identifying the site of carbon nanotube (CNT) agglomeration in nanocomposite samples by nondestructive shearography test. In this regard, several samples of epoxy sheets reinforced by multi-walled carbon nanotubes (MWCNTs) with different levels of agglomeration were prepared. To improve the quality of inspection results Design of Experiments (DOE) technique was used based on Taguchi’s method. Signal-to-noise analysis was utilized to evaluate the tests’ outputs. The optimization of the shearography parameters was conducted based on signal-to-noise ratio (SNR) graphs obtained from the aforementioned analysis. Data analysis indicated that the agglomeration factor has the greatest effect on the results, shear distance and loading size are placed in the next ranks respectively. According to the results, shearography has the potential to be used to verify the health of nanocomposites in mass production.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 12","pages":"1407 - 1419"},"PeriodicalIF":0.9,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143455639","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}
