Abstract
One important direction for the mechanical behavior study of the materials is the fracture surface evaluation. This work makes a qualitative interpretation of the fracture surface from some Zircaloy-4 SEM microfractographies by using the fractal analysis technique. By reason of the current research, we introduce for the first time some new algorithms, most of them based on Box Counting methods and variations for 2D and 3D structures. The Box Counting algorithm is an efficient algorithm to compute the Fractal Dimension and can be applied directly on gray-levels images.
