Nacre is well known for its high strength and toughness owing to its ingenious โbrick-and-mortarโ microstructure. However, its impact resistance has not been studied as well as its static properties, even though protecting fragile organs from external dynamic loadings is one of its most important functions.
Among all inspiring bio-material, Abalone seashell has its unique characteristics of high strength and toughness. Though , there is the general trend in materials that some of the toughness have been compromised for the sake of increasing hardness and vice versa. This astonishing property of sea shell attracts material scientists to understand the root cause for this property. One of such enthusiast, Prof. Kalpana Katti at North Dakota State University unlocked these secret of these phenomenon lies in its microstructure.
Biological materials in nature serve as a valuable source of inspiration for developing
novel synthetic materials with extraordinary properties or functions. Much effort to date
has been directed toward fabricating and understanding bio-inspired nanocomposites
with internal architectures mimicking those of nacre and collagen fibril. Here we establish
simple and explicit analytical solutions for both upper and lower bounds of the elastic
