This presentation first discusses the important features characterizing a hierarchal material system at various scales. It then demonstrates that such multi-scale hierarchy can effectively synergize the physical, mechanical and other important properties. It next deals with some theoretical issues associated with the disparity in hierarchal levels in material research. This talk examines these related topics with several approaches to not only reveal the underline geometrical and physical mechanisms, but also emphasize the ways in which such mechanisms can be applied to developing engineered material systems with novel properties. |
