Outline of Final Research Achievements	Many mysterious "spatial periodic patterns" casually exist in the natural phenomena that surround us. However, the occurrence of such casual spatial periodic patterns is thought to have some kind of rational meaning or mechanical necessity. This research provides a deep insight into the properties that form this spatial periodic pattern from the perspective of structural mechanics and structural stability theory, and theoretically interprets its fundamental meaning. The purpose is to create a social and structural system design philosophy that overturns concepts. During the research period, he developed a new academic field called "plant mechanics" and gained a lot of knowledge that will be useful in future manufacturing, and the results were published in numerous academic papers and books.
Free Research Field	構造力学
Academic Significance and Societal Importance of the Research Achievements	本研究で得られた成果は、主に植物の形状がもつ力学的意味から構造設計に生かす技術として昇華できる可能性を有している。学術的にもこれまでの植物学者が気づかなかった視点、方法論でのアプローチによる新しい発見が多く、多くの学術論文にてそれが評価をされている。また、この研究の集大成といえる研究代表者の著書「竹取工学物語　土木工学者、植物にものづくりを学ぶ」が2023年7月に岩波書店から「岩波科学ライブラリー」として出版され、広く一般市民にもその内容が公表されている。
