“…The fracture surface topography contains useful information: the loading history, the energy consumed on crack growth, the resistance of microstructural features against loading at crack front, extension of process zones, etc. Many techniques have been developed to measure fracture topography, being a large number of them based on scanning electron microscopy (SEM), including stereo reconstruction (Azevedo and Marques, ), frequency domain methods (Savary et al ., ), and direct measurement of fractal dimension data (Wzorek et al ., ). Stereo reconstruction quality mostly depends on the details revealed at the surface (Hein, ), with coating and beam voltage intensity being important issues.…”
