Fracture in biomimetic layered structures

Strong substances created in nature often take advantage of composite structures such as laminar structures (tooth, timber, nacre etc.) where hard layers are glued together by soft thin layers. We study fracture properties of such systems within a continuum elastic point of view, mainly at the scaling level. We may also present viscoelastic effects in steady crack propagation in such anistropic materials.
