摘要

利用几何精确的Cosserat理论，将Epipactis属陆生兰花具有平行脉络的叶片的静态特性建模为耦合弹性杆，并使用Shampine、Muir和Xu的方法对由此产生的边值问题进行了数值求解。叶片结构对所施加的力的响应是从初步测量中获得的。这些测量结果使得能够确定Epipactis叶片的杨氏模量。一些叶片出现褶皱和波动特征是由于叶片边缘的扭转刚度较小。

Mechanical Properties of Long Leaves: Experiment and Theory

The static properties of leaves with parallel venation from terrestrial orchids of the genus Epipactis were modelled as coupled elastic rods using the geometrically exact Cosserat theory and the resulting boundary-value problem was solved numerically using a method from Shampine, Muir and Xu. The response of the leaf structure to the applied force was obtained from preliminary measurements. These measurements allowed the Young’s modulus of the Epipactis leaves to be determined. The appearance of wrinkles and undulation characteristics for some leaves has been attributed to the small torsional stiffness of the leaf edges.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
