Abstract

Fractal analysis has been developed as a tool to analyze the fractal characteristics with less sensitivity to magnification over a wide scale, which can also be used to quantify the fractographic data. In this work, two different techniques of fractal analysis were used to calculate the fractal dimension. In the first method, the fracture surface morphology was utilized, and in the second method, the roughness profile of the fracture surface was utilized in order to calculate the fractal dimension. The purpose of the work is to compare the effectiveness of these two fractal techniques in characterizing the mode of fracture. For it, the results of fractal analysis were compared with the quantified results obtained using conventional fractography analysis. Moreover, fractal dimension obtained using roughness profile had a positive linear correspondence with impact energy, and this result has been discussed in terms of fracture micromechanism.
