The mirror-shadow multiple reflection method, based on measuring the velocities of longitudinal and transverse waves propagating along the rod diameter of the spring, is used to evaluate the nonuniformity of acoustic properties. Specially designed pass-through electromagnetic–acoustic transducers of transverse waves of axial polarization and transducers of longitudinal waves on the basis of flexible piezoelectric film of polyvinylidene fluoride provide multiple reflection of volume waves along the cross section of the coiled coil of the spring. The elasticity, shear moduli, and Poisson’s ratio are calculated based on the results of wave velocity measurements. It was established that the nonuniformity of acoustic and elastic properties along the length of the bar differs for automotive and railway springs. A linear variation of acoustic and elastic properties along the length of the coiled wire was observed in the railway spring (from one end to the other), caused by the technology of high-temperature mechanical processing. In the barrel-shaped automotive spring, a nonlinear variation occurs along the length of the coiled wire, correlating with the coil diameter and the formation of residual stresses.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 4","pages":"420 - 430"},"PeriodicalIF":0.9,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144107","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 bottom of ultrasonic transducer was designed into a curved surface to improve its coupling to the composite pipes. In accordance with the attributes of local defect resonance (LDR), the frequency band was ascertained by analyzing the displacement spectrum at the site of impact damage. The LDR frequencies were further validated from the thermal responses of ultrasonic thermography inspection and finite element analysis of the specimen eigenfrequencies. Finally, the method was used to detect various impact damage on CFRP pipes. Since the LDR frequency at the defect is covered by the frequency range of the narrowband sweep excitation, impact damages can be efficiently activated, resulting in an obvious temperature rise.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 4","pages":"465 - 480"},"PeriodicalIF":0.9,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144108","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}

In order to meet the demand of high-tech industries, the production technology of silicon wafer is supposed to meet the high-precision standard, and if the micro-cracks produced during grinding are not detected on time, the yield of a useful product will be reduced. In order to achieve more efficient detection of micro-cracks in silicon wafers, a scanning laser thermal nondestructive testing system was developed. Using the pseudo static matrix reconstruction algorithm, the experimental data has been converted into static images to provide easier defect detection and evaluation. The influence of geometric characteristics (length, width and depth) of micro-cracks and laser excitation power on surface temperature signals in the laser scanning tests has been studied. The image enhancement techniques, such as linear gray scale transformation, basic function transformation and histogram equalization have been compared. The effectiveness of using super-pixel segmentation, dual threshold segmentation, iterative threshold segmentation and UNet3+ network for improving micro-crack detection efficiency has been explored. Common segmentation techniques have not proven to be useful in the image enhancement because of the presence of noise. Better results in image segmentation have been achieved by using a UNet3+ network, which ensured identification accuracy of about 90% in the segmentation of micro-crack defects.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 4","pages":"450 - 464"},"PeriodicalIF":0.9,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144368","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 reliability of inspection is determined by the quality of the DFA image—resolution and signal-to-noise ratio. To achieve super-resolution of echo signals, which will lead to lateral super-resolution of reflectors, various methods are used: maximum entropy method, Bernoulli–Gaussian deconvolution, Lucy–Richardson deconvolution, methods of recognition with compression (CS), methods of construction of autoregressive models of signals, etc. To apply these methods, we need to know the impulse response of the ultrasonic inspection system. It can be measured, but you can use methods of “blind” deconvolution, which are used in image and signal processing. For example: the method of eliminating camera blur at its random displacement, maximum correlated kurtosis deconvolution (MCKD), cepstral analysis, etc. In this paper, a cepstral analysis method for super-resolution or for obtaining information about the impulse response of the system is considered to construct an AR spectrum model to obtain the lateral super-resolution of DFA-images.

It considers both analytical and finite element (FE) methods to analyse the vibration response of a simply supported beam carrying a moving mass and suffering from an open crack. Timoshenko beam theory has deliberated to investigate the dynamic behavior of a discretely simply supported beam with including shear deformation and rotational inertia under various configurations of open crack and moving mass conditions. The beam was divided into two segments, which obeyed the Timoshenko beam theory and the crack was modeled by a torsional spring with local elasticity at the connecting region of the two segments. The governing equations of the beam transverse vibration were solved based on Hamilton’s principle, and the obtained results are validated with previously published works, including numerical and experimental works. The effect of crack depth (CD) and crack location (CL) with the amount and speed of the moving mass on the dynamic response of the beam have been investigated, where the presence of the crack plays a key role in both free vibration characteristics and dynamic response of the Timoshenko beam. Hence, more nonlinearity and higher deflection in the dynamic behavior have perceived at CL = 0.5 and CD > 0.3 h. The obtained natural frequencies are generally decreased with increasing CD, in which significant drop in the 1st and 3rd natural frequencies have been identified when the crack is located at the mid-span of the beam. A frequency-domain representation under various mode excitations of moving load has evaluated to indicate the presence of the crack within the Timoshenko beam. Hence, the evaluation of frequency domain and dynamic deflection can be sensitive to indicate the presence of the crack and its severity.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 4","pages":"490 - 503"},"PeriodicalIF":0.9,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144111","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}

This article proposes an autoencoder-driven anomaly detection model for automatic defect detection in quadratic frequency modulated thermography. The proposed model utilizes the pretrained stacked denoising convolution autoencoder (SDCAE) to extract deep features and feed them to a local outlier factor (LOF) for defect detection. This work analyzes the performance of the proposed SDCAE-LOF on a quick-responsive mild steel specimen with artificially embedded defects of various sizes at different depths. The performance is compared with the CNN-based deep anomaly detection model and other autorncoder models using multiple metrics to confirm the superior defect detection capability of the proposed method.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 4","pages":"481 - 489"},"PeriodicalIF":0.9,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145144109","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}
