Experimental verification of the theoretical methodology for describing a material's fracture morphology using multifractal analyis of a stereometrically examined surface ( full 3D analysis) is presented. A high effectiveness of a multifractal analysis has been shown for a diversified multifractal spectrum width and for a quantitative description of overlaps. The values obtained are very similar to those obtained by the quasi 3D method [ 6] as well as by conventional analysis, that is analysis of the profile images obtained from transverse microsections. The method presented, however, is the least time-consuming, the cheapest and seems to be the most objective for fracture morphology analyses.
