Abstract
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.
