On April 25, 2025, Kyutech professor Emeritus Nao-Aki Noda and alumni were awarded the title of Fellow by the Society of Automotive Engineers of Japan.
The Society of Automotive Engineers of Japan
Established in 1947, it is Japan's largest academic organization in the engineering field, consisting of approximately 47,000 automotive researchers, engineers, and students, and approximately 700 corporate members.
Since its establishment, the aim has been to "contribute to the promotion of academic culture, the development of the industrial economy, and the improvement of people's lives.
"The aim has been to hold lectures to present research results, research issues and future technologies, and foster the development of next-generation engineers.
We promote training, publishing publications, awarding and encouraging outstanding research achievements, establishing automobile-related standards, and collaborating and interacting with related organizations and organizations.
Reason for Award
Adhesive bonding is becoming increasingly important in multi-materialization, which is the key to automotive safety and weight reduction.
In the JIS standard, adhesive strength is expressed as the average stress per bonded area of a small specimen, which corresponds to the position of elementary material mechanics ignoring the stress concentration at the bonded edge. In reality, the intensity of the singular stress field ISSF of the actual structure varies depending on the geometry and dimensions of the bonded area. Therefore, the strength of the real structure also varies depending on the ISSF.
This paper has discussed such variations in the average bond strength from the results of ISSF analysis. In particular, by matching the adhesive layer thickness between the small specimen and the actual structure as specified by JIS, the paper has clarified that the results of the JIS standard can be regarded as the tensile bond strength of the actual product.
Thus, this paper has provided an original and unified understanding of a question, “Can we evaluate the bond strength of real structures using adhesion specimens? Therefore, this paper is highly commended.
