J. Stampfl et al., RECONSTRUCTION OF SURFACE TOPOGRAPHIES BY SCANNING ELECTRON-MICROSCOPY FOR APPLICATION IN FRACTURE RESEARCH, Applied physics A: Materials science & processing, 63(4), 1996, pp. 341-346
Stereoscopic scanning electron micrographs can be used to reconstruct
the microscopic topography of material surfaces. By applying a system
for automatic image processing we can obtain Digital Elevation Models
(DEMs) of the investigated surface. These DEMs are used to measure the
degree of deformation on metallic fracture surfaces. By modelling the
deformation the amount of plastic energy that is necessary to shape t
he microductile fracture surface can be calculated. These values are c
ompared with experimentally obtained results.
