Fatigue damage severely impairs high-strength marine steel performance, threatening the safety of ships and offshore engineering structures. Due to the abrupt nature of structural fatigue failures, early detection of fatigue microcracks is crucial for ensuring structural reliability. The detection of fatigue damage was experimentally and numerically investigated in AH36 marine steel using nonlinear ultrasonic technique. According to the distribution features of fatigue damage in marine steel, a three-dimensional finite element model is proposed to investigate the nonlinear ultrasonic method for the detection of randomly distributed fatigue microcracks. The microcrack distribution is much closer to the actual state of fatigue microcracks in metal than that of previous studies which used two-dimensional plane strain models with the individual crack or distributed cracks. The high-harmonic was induced by the contact behavior of crack surfaces. The results revealed that the relative nonlinear coefficient increases with higher microcrack number and length, but decreases with larger microcrack width. Additionally, the FE model, which closely approximates the actual distribution of fatigue microcracks in metallic materials, provides a new research avenue for a more comprehensive understanding the nonlinear interaction between ultrasonic waves and fatigue microcracks.

疲劳损伤严重损害了高强度船用钢的性能,威胁着船舶和近海工程结构的安全。由于结构疲劳失效具有突发性,因此疲劳微裂纹的早期检测对于确保结构可靠性至关重要。利用非线性超声波技术对 AH36 船用钢疲劳损伤的检测进行了实验和数值研究。根据船用钢疲劳损伤的分布特征,提出了一种三维有限元模型,研究非线性超声波法检测随机分布的疲劳微裂纹。与之前使用二维平面应变模型的单个裂纹或分布式裂纹相比,该微裂纹分布更接近金属疲劳微裂的实际状态。高次谐波是由裂纹表面的接触行为引起的。研究结果表明,相对非线性系数随着微裂纹数量和长度的增加而增加,但随着微裂纹宽度的增加而减小。此外,该 FE 模型非常接近金属材料中疲劳微裂纹的实际分布情况,为更全面地了解超声波与疲劳微裂纹之间的非线性相互作用提供了新的研究途径。

In this study, the elastic properties of porous cylinders are evaluated using a nondestructive method based on ultrasonic wave propagation. In the scientific community, the elastic properties of materials play a crucial role. Measuring these properties can reveal valuable details about the mechanical properties of these materials. The scattering of a plane acoustic wave has received a great deal of attention from researchers due to its growing interest in many disciplines. Many authors have studied the acoustic scattering by means of cylindrical components (e.g. tubes, cylinders, etc.). This study shows how to analyze the distribution of circumferential waves with increasing porosity using the modal view of the waves propagating around the circumference of a cortical bone. This technique is applied on a signal backscattered by an porous tube of radius ratio b/a = 0.7 (a is the external radius and b is the internal radius). Our investigation revealed a correlation between bone porosity, fluid saturation, and pore radius, and changes in elastic properties. The Schoch model was developed to investigate the propagation of ultrasonic waves in porous bone. The results demonstrate the effectiveness of this approach for acoustic characterization and describing the impact of osteoporosis on bone elasticity.

本研究采用基于超声波传播的无损方法对多孔圆柱体的弹性特性进行了评估。在科学界,材料的弹性特性起着至关重要的作用。测量这些特性可以揭示有关这些材料机械特性的宝贵细节。由于平面声波的散射在许多学科中日益受到关注,因此受到了研究人员的高度重视。许多学者通过圆柱形部件(如管、圆柱等)对声散射进行了研究。本研究展示了如何利用波在皮质骨圆周传播的模态视图,分析随着孔隙率增加圆周波的分布。该技术应用于半径比为 b/a = 0.7(a 为外部半径,b 为内部半径)的多孔管反向散射的信号。我们的研究揭示了骨孔隙率、液体饱和度和孔隙半径与弹性特性变化之间的相关性。我们开发了 Schoch 模型来研究超声波在多孔骨中的传播。结果证明了这种方法在声学表征和描述骨质疏松症对骨弹性的影响方面的有效性。

The meso-damage process of Q355E steel metal used in wind power tower is accompanied by the release of transient stress wave. The information of stress wave can be collected by acoustic emission detection technology. However, due to the lack of intuitive and visual means, it is difficult to quantitatively evaluate the meso-damage of metal materials by acoustic emission information. In this paper, Deben Microtest 2kN in situ tensile test bench, FEI Quanta 450 field emission scanning electron microscope and SAEU2S acoustic emission acquisition system are combined to build a dynamic observation experimental system of acoustic emission source. The results show that there is a good correspondence between the in situ tensile displacement-load curve and the amplitude history of the acoustic emission signal. At different stages of in situ stretching, the acoustic emission signal has characteristic signals. The changes of the microstructure of the samples were observed, and the characteristic acoustic emission signals during the stretching process were analyzed by parameter analysis and waveform analysis.

The nuclear thickness gauging systems play an important role in the industry for invasive, online, and continuous measurements. The goal of the Beta thickness gauge is to obtain a precise measurement of thin films in which the performance of these gauging systems and output data quality are evaluated with the parameters including resolution, contrast, etc. The choice of the emitted suitable energy distribution of the Beta source is one of the effective factors in the system performance and precise measurement of thin films. In this research, a Beta thickness gauge with 147Pm and 85Kr sources was simulated and evaluated in biaxially oriented polypropylene sheet production lines in order to calculate the system performance due to Beta emitter sources with different energy distribution and select the suitable Beta emitter source. The relative error percentage, standard deviation, resolution, and contrast parameters for 147Pm energy distribution were calculated 1.413, 0.113, 0.007, and 0.008, respectively. Also, these parameters for 85Kr energy distribution were measured 2.750, 0.220, 0.014, and 0.001, respectively. The results reveal that the 147Pm energy distribution has superior in comparison with the 85Kr energy distribution for measuring of films or sheets with thin thickness.

The electrical capacitance tomography (ECT) is a visual nondestructive testing technology. The relative positional distribution between the electrodes and the phantom object affects the accuracy of the reconstructed image. To solve this problem, an image reconstruction method and image fusion algorithm of ECT system based on rotating electrodes are proposed. First, 4 image reconstruction algorithms are employed to reconstruct the experimental model, the Landweber iterative algorithm based on Tikhonov regularization presents the best performance. Then, by rotation the 12 electrodes 4 times, we can obtain 5 sets of capacitance data, and obtain 5 images. Finally, the fusion results can be obtained by performing the adaptive weighted fusion on these 5 images. Results show that the adaptive weighted image fusion method based on rotation electrodes improves the quality of reconstructed images and effectively reduces the artefacts.

Static tests of AFM carbon fiber samples made by autoclave and vacuum molding methods were carried out. Acoustic (acoustic emission and ultrasonic) methods, strain gauging, and microanalysis of thin sections were used to test for defects. The location of acoustic emission signals in the area of stress raisers made it possible to establish that the number of defects in autoclave molding is ten times less than under vacuum molding. Ultrasonic and acoustic emission methods, strain gauging, and microanalysis allowed determining the structure of AFM carbon fiber, the coordinates of defects, and their type. During the testing of unloaded samples made by vacuum molding, manufacturing defects were found that grew in size during static stretching and led to the occurrence of new destructions. No manufacturing defects were found in the samples produced by autoclave molding. Microanalysis of samples produced by the vacuum method revealed defects associated with fiber destruction, matrix cracking, and delamination. Tests of samples prepared by autoclave molding have shown that there are practically no defects in them.

A comprehensive experimental study was conducted on EN8 steel samples subjected to hot rolling at various temperatures and with different numbers of passes. The research investigates the influence of these rolling parameters on the material’s microstructure, hardness, and magnetic properties. The study includes controlled heating to specific temperatures, precise adjustments of roll spacing, and meticulous monitoring of rolling parameters. Key findings include the microstructural evolution during hot rolling, with grain refinement and phase transition, notably influenced by temperature. The data also reveals the relationship between rolling conditions, material hardness, and percentage of recrystallization, offering insights into optimizing material properties. Furthermore, the study presents an in-depth analysis of the Barkhausen peak’s behavior concerning temperature, showcasing its potential for non-destructive hardness evaluation. Overall, this research provides valuable knowledge for material engineers and manufacturers aiming to tailor EN8 steel properties through optimized rolling and heat treatment processes.

This article continues and supplements the article with the same title published in Russian Journal of Nondestructive Testing, no. 1, 2022, which provides six ways to assess the quality and reliability of semiconductor products (SCPs) using low-frequency (LF) noise parameters. This paper presents a generalization of the results previously obtained by the authors and describes four more methods for diagnosing and evaluating the reliability of SCPs by varying the parameters of low- frequency noise under additional external influences such as electrostatic discharge and (or) thermal annealing. It is shown that additional impacts make it possible to increase the reliability of the assessment of the SCP reliability.

本文是对《俄罗斯无损检测杂志》(Russian Journal of Nondestructive Testing)2022 年第 1 期发表的同名文章的延续和补充,该文章提供了使用低频(LF)噪声参数评估半导体产品(SCP)质量和可靠性的六种方法。本文概括了作者之前取得的成果,并介绍了另外四种诊断和评估 SCP 可靠性的方法,即在静电放电和(或)热退火等额外外部影响下改变低频噪声参数。结果表明,附加影响可以提高 SCP 可靠性评估的可靠性。
