报告大纲： 

Structuralhierarchy and thus heterogeneity are inherent features in biological materials,but their significance in affecting the system behaviors is yet to be fullyunderstood. This presentation first discusses the important featurescharacterizing a hierarchal material system at various scales. It thendemonstrates that such multi-scale hierarchy can effectively synergize thephysical, mechanical and other important properties. It next deals with sometheoretical issues associated with the disparity in hierarchal levels inmaterial research. This talk examines these related topics with severalapproaches to not only reveal the underline geometrical and physicalmechanisms, but also emphasize the ways in which such mechanisms can be appliedto developing engineered material systems with novel properties.
