“…Similarly, it can be seen that item ref_325_y25 has lost all its shape by torsion, Figures 12a and 12b. Also, of potential significance is the enhanced results offered by the processed image of the items internal texture and porosity which informs the investigator of the manufacturing processes (Lang & Middleton, 2016;Yahaghi, Madrid, & Movafeghi, 2020), see Figures 13a and 13b relate to the metal fragment ref_894_1 where the processed image focuses on the internal granulometry of the fragment. Similarly, for item ref_895_4, which corresponds to an iron tape with metal rivets which is thought to be from a decorative element, Figure 14a.…”

Archaeologists and conservators have different problems in inspecting metal-type pieces extracted from the archaeological sites, such as their large number and the complexity of the materials and their shapes. Usually, all of the pieces are hidden under the oxidation layers. From this point of view, a non-destructive analysis technique such as digital radiography imaging can detect and discriminate one piece from another. Also, the shape of pieces, state of the metal core, and assessment of its handling can be investigated. But there are still some problems with metal-type parts with a certain thickness. The generated X-ray image can be very foggy and without adequate quality. This will prevent the method to discriminate small details about the shape, hidden structures, and the real level of oxidation, and the presence of cracks. A solution for improving the quality of the x-ray image can be implementing a digital imaging processing algorithm for enhancing the quality of the radiographs. In this study, the metal parts are carried out from two important Iberian-Roman sites located on the coast of the municipality of Burriana (Castellón), i.e. Sant Gregori and Torre d'Onda. This set of pieces belong to the archaeological museum of Burriana, Spain, and are investigated by X-ray imaging. This study has used the “Fast 2D Gaussian convolution first-order infinite impulsive response” (IIR) to extract the maximum detail for better interpretation of the image. A multidisciplinary perspective has been desired for this study.

“…Moreover, the spacing and orientation of the crystal lattice can further prompt diffraction effects in scattered radiation, exerting additional influence on the scattering phenomena observed [59][60][61]. To enhance the reliability of detection, it is necessary to improve the signal-to-noise ratio and contrast of the images [15]. In this regard, digital image processing algorithms, such as the total variation method, optimized neural networks, and sparse methods, are widely used for image enhancement.…”

“…The morphology and location information of cracks can be obtained by the leakage magnetic field. In the early days, a series of methods were explored based on fundamental physical principles, such as eddy current testing (ECT) [10][11][12], magnetic particle testing (MPT) [13,14], penetrant testing (PT), ultrasonic testing (UT), and radiographic testing (RT) [15][16][17], which have been extensively utilized for the detection of metal cracks, among other defects. These methods have been refined over time and honed to address specific challenges posed by different materials and operating environments.…”

There are high demands for the early and reliable detection of metal components used in safety-critical structures. Nondestructive testing (NDT) is a pivotal technique used across industries to assess a material’s integrity without causing damage and has been used in early crack detection of metals, mainly based on changes in the crystal structure and magnetic properties of metals. This review provides an overview of internal and external detection technology based on nondestructive testing methods such as ultrasonic, electromagnetic, ray, magnetic particle, etc. Especially, the integration of advanced methodologies such as machine learning and artificial intelligence deserves a place in NDT methods. Furthermore, the multifactorial detection method is promoted to enhance the sensitivity and detection range due to advantage integration but still has emerging challenges for safer equipment and applications. The review aims to compare these methods and outline the future challenges of NDT technologies for metal crack detection.

This paper explores the development history and modern design innovation of Chinese ceramic packaging containers through multivariate statistical analysis, revealing their essential role in the market and cultural heritage. The development history and contemporary design innovation of Chinese ceramic packaging containers are studied in depth. The study finds that ceramic packaging containers have evolved from prehistoric hand-kneaded small pieces to the present, constantly incorporating new crafts and cultural elements. Regarding formal aesthetics, the use of rhythm and rhyme in ceramic packaging containers grew at 81.13% between 2015 and 2020, suggesting that designs tend to be more dynamic and expressive. Data analysis shows that the key factors influencing the design of ceramic packaging containers include process technology, trade development, cultural concepts and religious beliefs. Regression analysis indicates that these factors significantly positively impact the design quality of ceramic packaging containers, with a model fit of 63.52%, revealing that these factors jointly promote the improvement of design quality. Innovative combination of traditional elements and modern technology is the key to fostering innovation of ceramic packaging container design and cultural heritage. The market competitiveness and cultural value of ceramic packaging containers can be effectively promoted by emphasizing the development of craft technology and the integration of cultural elements.
