Domestically produced polytetrafluoroethylene (PTFE) was used as an ionizing radiation detector. Detector samples were irradiated with accelerated electrons with an energy of 10 MeV with doses from 10 to 50 kGy. After irradiation, the intensities of the EPR and TL signals were measured from each detector. The dependence of the EPR signal intensity on the radiation dose was linear. The TL parameters were equal to: maximum temperature ({{T}_{{text{m}}}} = 164~^circ {text{C}}), form factor ({{mu }_{g}} = 0.45), frequency factor (S = 4.44 times {{10}^{{11}}};{{{text{s}}}^{{ - 1}}}), activation energy (E = 1.14) eV. The spectral composition of TL had a wide band with a luminescence maximum of approximately 425 nm. The dose dependence of the TL output was also linear in the studied dose range. Annealing of EPR and TL signals occurred in the same temperature range, 160–240°C. The correlation of dose dependences of normalized intensities of EPR and TL signals, the similarity of their temperature ranges of annealing intensities, indicated that the EPR and TL properties of PTFE detectors are associated with changes in the charge states of the same centers.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 7","pages":"797 - 803"},"PeriodicalIF":0.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242753","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 cases of its testing by acoustic emission, ultrasonic methods and strain gauging during the simulation of horizontal aircraft landing and during the simulation of landing with a side impact are considered. During the spring tests, strain gauge was used, and tensile, compressive and torsional deformations were studied. The changes in the main informative parameters of acoustic emission signals (MARSE energy parameter, median frequency, structural and two-interval coefficients) were analyzed. The defect type was determined using a modified structural coefficient. This made it possible to increase the speed of information processing, since its decrease corresponded to the matrix destruction, and its increase corresponded to the fiber destruction. The location of acoustic emission signal sources corresponding to the structure area with the greatest relative deformations was obtained. It was noted that when simulating a horizontal landing of an aircraft, after removing the load, residual deformations were observed in the spring material.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 7","pages":"725 - 736"},"PeriodicalIF":0.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242752","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 resonant element consists of a metal spiral structure (MSS) on a defected ground, which excites the SLSPs. This resonator is connected to linearly polarized, ultra-wideband, high-gain microstrip patch antennas to enable wireless extraction of strain information. A coupled metallic plate is incorporated in the SLSPs resonator to form a capacitive coupling, thereby completing the wireless strain sensor design. As the material under test (MUT) undergoes stress-induced strain, the separation between the sensor’s two plates changes, shifting the resonant frequency. Two log-periodic antennas are employed for wireless signal transmission and reception, allowing the strain magnitude to be determined from this frequency shift. Experimental results show that the proposed sensor can detect a minimum deformation of 0.01 mm, with a sensitivity up to 574.2 kHz/με, representing a substantial improvement over traditional near-field resonant strain sensors. The proposed sensor enables high-precision wireless monitoring of small strains in the MUT, offering a highly flexible and noninvasive approach for structural health sensing.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 7","pages":"825 - 839"},"PeriodicalIF":0.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242674","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 influence of various welding parameters on the residual stresses in welded workpieces is analyzed using finite element simulation software. The results indicate that the maximum equivalent stress in the weld seam is inversely proportional to the welding speed and directly proportional to the welding current. Subsequently, two SUS301L austenitic stainless steel plates are selected as the welding materials, and metal inert gas (MIG) welding is employed for flat plate welding. Residual stresses in different regions of the welded workpieces are measured using a three-directional ultrasonic testing method and validated against the simulation data. A high degree of agreement is observed between the two, thereby demonstrating the feasibility of this ultrasonic method for detecting planar stress.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 7","pages":"750 - 767"},"PeriodicalIF":0.9,"publicationDate":"2025-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242833","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 investigation focuses on the influence of composite’s anisotropy and the tilt of the non-contact transducer on the directivity diagrams, frequency response, and dispersion properties of the guided waves excited in the plate. The wave field is described by the solution of the coupled problem for the system source–acoustic-medium–composite-plate obtained in the form of the inverse Fourier transform path integrals of the waveguide Green’s matrix and source parameters. The residual technique and the stationary phase method gives an explicit physically visual representation for the guided waves excited contactlessly in the composite plate. Utilizing this framework, the optimal transducer tilt angles for exciting waves of the desired type at specific center frequencies are determined. Numerical results demonstrating the dependence of the amplitude–frequency characteristics of the excited waves and the optimal transducer tilt angle on the sample’s structure and elastic properties are presented.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 6","pages":"610 - 619"},"PeriodicalIF":0.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011604","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 utilises halogen lamps as the heat source and implements three excitation techniques: pulse thermography (PT), lock-in thermography (LT) and frequency modulation thermal wave imaging (FMTWI); along with that, it compares two post-processing approaches, cross-correlation (CC) and frequency domain phase (FDP) on the obtained thermal images. The signal-to-noise ratio (SNR) is considered a figure of merit for evaluating the effectiveness of each technique and its associated post-processing approaches. The results demonstrate that the CC post-processing technique consistently outperforms the FDP method in enhancing defect visibility and improving SNR values across all excitation techniques and configurations. This research highlights the potential of IRT as a reliable, non-destructive testing method for detecting and characterising defects in a chosen CFRP test sample.","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"61 6","pages":"704 - 714"},"PeriodicalIF":0.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011834","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}
