Abstract

The verification and fundamental design concepts of structural links in biological bulk and surface materials, using multi-million atomistic simulations, were focused. The flaw tolerant design of biocomposites, where a long crack embedded in a thin strip of material, was discussed. The design of biological contact elements for optimal adhesion was also described. The atomistic simulations reveal a smooth transition between Griffith mode of failure via crack propagation to uniform bond rupture at theoretical strength below a nanometer critical length. The atomistic simulations support the hypothesis that materials become insensitive to flaws below a critical nanometer length scale.
