摘要:

Induction is one of the important methods of reasoning in logic. It starts from specific observations and measures to detect patterns and regularities, then formulates some tentative hypotheses that can be explored and demonstrated, and finally ends up with some general conclusions or theories. Such inductive approach has been successfully used in our studies aiming at revealing mechanics concealed in biological materials and structures with unique properties and capabilities. In this talk, three examples of our success are presented. More specifically, from the teeth of black carp, we revealed the method to control the fracture mode of laminated composite; from the shells of mollusks P. placenta and abalone we uncovered a reinforcing mechanism for laminated composite by using spiral interface; from the leaves of mangrove, we learned an antifouling strategy by controlling surface morphology. All these findings not only provide insights into the mechanics responsible for the unique properties and capability of the biological materials and structures, but also imply great promise of application in the design of novel biomimetic advanced materials.
