Abstract
The description of rough fracture surfaces has been an important challenge for many years. Showing at the fracture surface of a specimen, one realizes that the self-affine geometry of crack faces results from the stochastic nature of crack growth and can treat the fracture surface like as a fractal. Therefore the modelling a crack as a fractal and characterizing it by a fractal dimension has become the focus of research in recent years
