摘要:

历经上亿年,大多数龟类爬行动物均进化出了比重轻、强度高、韧性好的防护外壳。研究这些龟壳的结构特征和材料力学行为对安全防护结构的仿生设计有着重要启示。本文分别从龟壳的宏微观多尺度结构--功能关系、静动态力学性能和仿生应用三个方面介绍了近年来国内外的研究进展及现状。基于对上述研究现状的分析,本文还进一步展望了龟壳力学性能研究未来需关注的重点,以期能够更好地促进仿龟壳结构在安全防护领域的应用。

Abstract:

After the evolution of hundreds of millions of years, most turtles have developed excellent shells with high specific stiffness and toughness. Obviously, the multi-scale structural characteristics and the biological material mechanical behavior of these turtle shells can be used for promoting the bio-inspired design of safety protection structures. This paper reviews the research progress of the turtle shell relevant to its protective functions, including the macro and micro features of the carapace and the corresponding mechanical properties. In addition, some carapace-inspired designs that could be adopted in protection structures are summarized. Finally, the existing problems and the focus of the future research are discussed, to provide some food for thought in the bio-inspired design of safety protection systems in future.

Key words: turtle shell, mechanical properties, protection structure, bio-inspired design
