NANOMECHANICS OF BIOLOGICAL SYSTEMS——WHAT CAN WE LEARN FROM NATURE ABOUT THE MECHANICAL PRINCIPLES OF HIERARCHICAL ATERIALS?
Multi-level structural hierarchy is a rule of nature.Hierarchical structures can be observed in all biosystems from chromosome,protein,cell,tissue,organism,to ecosystems.Mechanics of hierarchical materials inspired by nature may provide useful hints for both materials engineering and biomedical engineering.What are the roles and principles of structural hierarchy? What determines the size scales in hierarchical materials? How to design hierarchical materials with designated mechanical and other properties/behaviors? My group has been attempting to address some of these questions during the recent years 1-15.Here we consider two idealized,self-similar models of hierarchical materials 10,11,14,15,one mimicking geckos attachment system and the other mimicking the mineral-protein comnosite structure of bone.
