Date of Award：2025.6.20 Name, Faculty/Graduate School: Osamu SAITO (Institute of Industrial Science, Former Research Associate), Weikun CHEN (Department of Systems Innovation, D3), Zeyu DONG (Department of Systems Innovation, Ph.D. Graduate), Yoji OKABE (Institute of Industrial Science, Professor) Name of the award and a short explanation about the award： Best Paper Award at the Japan Society for Non-Destructive Inspection The awards will be presented to papers published in JOURNAL of The Japan Society for Non-Destructive Inspection, in 2023 or 2024, that are recognized for academic and technical excellence, with the aim of improving non-destructive inspection technology. About awarded research：This paper focuses on the detection of delamination in honeycomb sandwich structures used in the aircraft and space industries through proposing a new non-destructive inspection method that utilizes the dispersion characteristics of guided waves. This inspection method can be easily applied to complex shapes and large-scale structures, which requires a substantial effort to inspect using conventional techniques. In addition, non-contact inspection was achieved using laser ultrasonic technology, and the accuracy of delamination detection was dramatically improved through the development of a signal processing method based on experimental data. The results presented in this paper are expected to contribute to the efficiency and cost reduction of maintenance work on aircraft structures, as well as ensuring safety, and to the academic development in the field of non-destructive testing. Awardee’s impression & future plan：We are really honored to receive this prestigious award. Our laboratory will continue to work on research into ultrasonic damage detection methods and hope to make further contributions to the development of the fields of non-destructive testing and structural health monitoring.
