The relationship of Thomsen anisotropic parameters to the crack density of a cracked medium

Kangan Fang, R. James Brown

In this paper,we first compute the effective stiffness tensor and Thomsen anisotropic parameters in the cracked media in which anisotropy is caused by stress aligned fractures or cracks with a particular crack density. We then analyze the variations of velocities versus crack density and phase angle and we are able to relate velocities to the crack density directly.
