生物材料力学研究新进展

Recent developments in mechanics of biological materials:A brief review

作为生物力学中一个快速发展的重要研究领域,生物材料力学旨在通过实验研究和理论分析,揭示各种天然生物材料的功能、性能、结构和组分之间的基本关系和机理,并为新材料的仿生设计等提供来自大自然的启示。本文综述了近年来我国学者在该领域取得的一些最新研究进展,主要内容包括珍珠母、牛角等生物复合材料的强韧化机制,生物材料表面浸润特性与微纳米结构之间的关系,以及相关的一些仿生应用。本文还简要介绍了本期专刊所刊登的7篇邀请文章。

As a rapidly developing area in biomechanics,mechanics of biological materials aims to investigate the fundamental relationship between functions,properties,structures,and compositions of various natural biological materials at different length scales and the underlying physical mechanisms through experimental research and theoretical analysis,and to provide inspirations from the splendid living world for the biomimetic design of new materials.In this paper,some recent achievements,mainly made by Chinese scholars in this field,are briefly reviewed,including the stiffening and toughening mechanisms of such biological composites as nacres and horns,the relation between the surface wetting behavior and the micro/nanostructures,and some relevant biomimetic applications as well.The contents of seven invited papers published in this special issue are also introduced.
