英文摘要: Abstract:
The biological world is replete with composite structures of various kinds, which could be teaching us important lessons in terms of assemblies sophistication and ensuing mechanical property optimization. For example, in nature high toughness is generally provided by means of multiscale (from nano to macro) fibrous composites, rather than with composite structures at a single scale. This will be illustrated by means of examples taken from our recent research with synthetic layered structures based on the turtle carapace [1,2], sponge spicules [3,4], and tendon-like multiscale unidirectional structures [5-8].

报告人: Prof. Daniel Hanoch Wagner
报告人简介: Bio:Born in Israel, Prof. Daniel Hanoch Wagner lived in Brussels, Belgium, where he earned a Licence in Physics from the ULB - Free University of Brussels (1975). He was awarded an MSc degree in Materials Science from the Hebrew University of Jerusalem (1977), and completed a PhD there in 1982. He spent three years (1982-1985) at Cornell University as a postdoctoral associate and lecturer. Prof. Wagner joined the Weizmann Institute's Department of Materials Research (now the Department of Materials and Interfaces) in 1985. He permanently holds the Livio Norzi Professorial Chair in Materials Science.
