Abstract
  • We investigate the elastic properties of multicracked solids by considering dispersions of elliptic cracks with arbitrary nonrandom orientational distributions. We provide a unified theory covering all of the possible orientational distributions, ranging from the totally random one to the distribution where cracks are preferentially oriented in a given direction. We especially focus on the orthorhombic symmetry and transversely isotropic symmetry for the cracks distribution. In both cases, the elastic behavior is proved to depend upon the density of cracks and upon some order parameters. Finally, the regime of large crack density and isotropic orientation is studied by means of iterated homogenization and it is shown that the effective elastic moduli depend exponentially on the crack density.
