Abstract

original image

Bioinspired by an extremely tough biocomposite, nacre, we performed numerical calculations of the layered structure in the presence of a crack. The crack-tip stress for the model composite is turned out to be significantly mitigated as demonstrated by the inset, following the simple scaling law. For further details see the article by Ko Okumura et al. on page 522.
