Evaluation Timber Mechanical Properties Through Non-Destructive Testing: A Bibliometric Analysis

With an increasing emphasis on sustainable construction practices, timber has become a pivotal material in architectural and construction industries. This ar-ticle presents a comprehensive bibliometric analysis aiming to identify trends in assessing mechanical properties in timber structures, Focusing on the Elasticity Modulus. Employing non-destructive testing methods, particularly ultrasonic waves using VOSviewer software, we scrutinized 129 documents from Scopus. Our bibliometric mapping strategy encompasses generic ('wood' OR 'Timber' AND 'non-destructive testing methods' AND 'mechanical properties'), medium ('wood' OR 'Timber' AND 'non-destructive testing methods' AND 'Ultrasonic wave method' AND 'mechanical properties'), and specific ('wood' OR 'Timber' AND 'non-destructive testing methods' AND 'Ultrasonic wave method' AND 'modulus of elasticity') search criteria. An additional layer of exploration is in-troduced with the inclusion of the keyword 'Heviz.' results reveal a substantial increase in research papers since the early 2000s. However, a discernible gap in literature, particularly in the assessment of mechanical properties, especially modulus of elasticity using ultrasonic wave methods, suggests weaknesses in links within the current body of knowledge. In conclusion, i) the abundance of collected documents resulted in more clusters; ii) the term "nondestructive ex-amination" is the most frequently used as predominant keyword, indicating a focus on research articles; and iii) the lack of studies indicates an untapped op-portunity for future research efforts, especially on strength and durability in wooden structures within the specific context of the Heviz Center, leveraging advanced methods such as ultrasonic waves. This article provides a critical overview of existing literature and highlights unexplored avenues in wood en-gineering research.
