Crack Models for a Transversely Anisotropic Medium

  title={Crack Models for a Transversely Anisotropic Medium},
  author={C.-H. Him Cheng},
A commonly used model for a transversely anisotropic crack rock is that by Hudson (1980, 1981). This model is based on a simplified analysis of a thin circular crack, with displacement and stress conditions specified on the boundary. These papers have a second order correction in addition to the first order term in porosity/crack density. In this paper we compare the results of Hudson with those of Anderson et al. (1974) and Cheng (1978) using the long wavelength static approximation and the… CONTINUE READING
