      abstract     = {Soft constituent materials endow biological composites,
                      such as bone, dentin and nacre, with viscoelastic properties
                      that may play an important role in their remarkable fracture
                      resistance. In this paper we calculate the scaling
                      properties of the quasi-static energy release rate and the
                      viscoelastic contribution to the fracture energy of various
                      biological composites, using both perturbative and
                      non-perturbative approaches. We consider coarse-grained
                      descriptions of three types of anisotropic structures: (i)
                      liquid-crystal-like composites, (ii) stratified composites,
                      (iii) staggered composites, for different crack
                      orientations. In addition, we briefly discuss the
                      implications of anisotropy for fracture criteria. Our
                      analysis highlights the dominant lengthscales and scaling
                      properties of viscoelastic fracture of biological
                      composites. It may be useful for evaluating crack velocity
                      toughening effects and structure-dissipation relations in
                      these materials. (C) 2011 Elsevier Ltd. All rights
