Nevertheless, these structures have certain drawbacks, including limited tensile strength and malleability, resulting in cracks within the edifices. These cracks have the potential to permit the ingress of chlorides, leading to corrosion of the reinforcement. In order to effectively address issues of quality control, upkeep, and strategic renovation of these buildings, it becomes imperative to employ a suitable nondestructive testing and assessment technique for comprehensive surveillance aimed at early detection of hidden rebar corrosion. Infrared thermal wave imaging has arisen as a feasible method for the nondestructive examination and assessment of reinforced concrete structures. This is attributed to its ability to perform comprehensive, remote, and rapid inspections, facilitating the monitoring of subsurface rebar corrosion. The current section introduces an innovative approach known as Digitised frequency modulated thermal wave imaging (DFMTWI) within diverse thermal nondestructive testing methodologies.

Ultrasound is the only nondestructive method so far to measure the residual stress of in-service components. However, for parts with material anisotropy, such as materials processed by rolling, the measurement accuracy is highly restrained. In this paper, a rolled 316L stainless steel sample is used to study the influence of texture on the measurement of residual stress by ultrasonic surface wave. The experimental results show that the propagation velocity of surface waves in the sample has anisotropic characteristics. The wave velocity parallel to the rolling direction (0°) is the maximum, and the wave velocity perpendicular to the rolling direction (90°) is the minimum, thereby affecting the measurement accuracy. It is found that reducing the frequency of surface waves can reduce the influence of anisotropy. Therefore, a low-frequency method and modified formula are used to improve the measurement accuracy. The maximum error in the rolling direction is reduced from 21.3 to 3.6 MPa, and the maximum relative error is also reduced from 45.4 to 9.0%. The modified formula can further reduce the influence of anisotropy, with the maximum error value further reduced to 2.3 MPa, the maximum relative error reduced to 4.9%, and the surface wave detection accuracy effectively improved.</p>","PeriodicalId":764,"journal":{"name":"Russian Journal of Nondestructive Testing","volume":"60 5","pages":"513 - 521"},"PeriodicalIF":0.9,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1061830924600084.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142212930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present article is devoted to the analysis of the first and partly fourth of listed factors. The review of reflectors, the use of which is regulated in various standards, is carried out. Advantages and disadvantages of flat-bottomed holes, segmental and corner reflectors (“notches”), lateral (SDH) and vertical cylindrical holes, and grooves are noted. Taking into account the specific features of ultrasonic wave scattering, it is noted that artificial “reflectors” such as “grooves” and SDHs are used to adjust the parameters of modern diffraction testing methods. It is recommended to expand the use of grooves, SDHs, and vertical drilling when revising the standards governing the use of conventional echo methods. The estimation of accuracy of measurement of defects parameters, first of all, the crack tip coordinates, with application of modern digital methods of information processing during ultrasonic testing is given. It is indicated that to increase the measurement accuracy and to determine the position and orientation of cracks in welds, it is necessary to create a database of digital twins of samples with artificial reflectors and products with real defects.

The study was applied to concrete specimens for which a compositional parameter which is the water-to-cement ratio (W/C) has been varied. The latter affects the density and porosity of the material and therefore its mechanical properties. In addition, the evolution of acoustic and mechanical parameters of the concrete during its curing period has been investigated. \u0000The acoustic velocity and attenuation parameters are determined by exploiting the time of flight and the amplitude of the received ultrasonic signals. This study shows that the variation of the water-to-cement ratio affects the velocity of propagation of the surface waves and also leads to a variation of the mechanical strength of the concrete. It concludes that there is a strong correlation between the strength of the concrete, the ultrasonic velocity, and the W/C ratio. The results obtained by the destructive evaluation, which provides a measurement of the compressive strength by mechanical crushing test, confirm those obtained by the non-destructive evaluation of concrete.
