Real, experimental ultrasonic data is often scarce, and while it is already known that finite element (FE) modelling produces data which is sufficiently realistic to augment real data, the computational cost associated with its generation at the scales required for the aforementioned purposes is often prohibitive. In this work, we propose the use of interpolation techniques in combination with results from FE modelling to rapidly generate more data without the need to solve additional FE models. We present the relevant methods to achieve this, and validate them through four exemplary cases of increasing complexity. Validation is achieved through the comparison of interpolation-generated results to those generated by full FE modelling, demonstrating that our method is capable of producing results for different physical setups and signals of various degrees of complexity. The results were typically within less than 1% away from the expected, but generated at a fraction of the typical computational cost, and, while the validation cases examined are of interest to the NDE community, the method extends to other fields where ultrasonic data is of interest.</div></div>","PeriodicalId":23522,"journal":{"name":"Ultrasonics","volume":"158 ","pages":"Article 107823"},"PeriodicalIF":4.1,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145158182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although accurate detection of microholes is critical for ensuring product safety, there is limited research in the open literature on the application of nondestructive testing (NDT) methods for detecting microholes in envelope materials. In this study, the air-coupled ultrasonic (ACU) method was applied for the first time to detect microholes in envelope materials. The influence of ultrasonic focusing and attenuation effects (along the propagation path) on the detection results was investigated by theoretical analysis and numerical simulations. Experiments were conducted to evaluate the microhole detection performance of transducers with different frequencies and focal lengths.

However, locating undetected signals from defects remains a significant challenge, especially when balancing cost and accuracy due to CFRP’s anisotropic propagation properties. This paper presents an innovative method named virtual-to-real mapping for generating undetected signals using only two AE sensors, which realizes a cost-effective solution for data collection. First, simulated signals are generated based on velocities obtained from two distinct fiber arrangements using two AE sensors. Then, one AE sensor is used to collect the experimental time-domain waveforms. An Auto-encoder maps the experimental and simulated signals to predict missing waveforms, which are validated through both quantitative and qualitative analyses. Incorporating these generated signals into a multilayer perceptron model results in an average improvement of 21.1% in multiple missing region classification accuracy and an average of 43.9% in independent missing region classification accuracy, providing valuable insights into data-driven methods for predicting and localizing missing defects in CFRP structures.
