Abstract

Grass and horn keratin are presented as examples of biological materials which are notch-insensitive due to the presence of strong and stiff parallel fibres in a weaker more compliant matrix. A simple Voigt model is adequate to account for most of these properties. The biological significance of this morphology is explored: with grasses it affects the way animals graze, with horn keratin the behaviour of the horned animal maximises fracture control.
