基于仿生学的材料疲劳损伤修复研究进展

Development of Recovery for Fatigue Damage of Materials Based on Biomimetic Science

回顾了基于仿生学的材料疲劳损伤修复研究的近期进展,介绍了该研究领域的2个发展方向:一是模拟生物体对自身较轻微损伤的自诊断、自修复功能,采用某种技术实施手段来达到控制材料失效或延长使用寿命的目的;二是模拟生物信息流处理系统映射载荷、损伤状态之间的关系,来实现对材料损伤状态变化的模拟。分别分析了这2方面研究的仿生学机理,并进行了实例归纳。对其进一步的研究将推动材料损伤修复的工程应用。

Recent developments on the studies of biomimetic recovery for fatigue damage of materials are reviewed. Research models are furthering in two directions: Technologies simulating damage self-recovery are studied to control damage or life-span; message channel dealing with relationship between stress and fatigue is simulated. Biomimetic mechanics of these studies is discussed.
