Abstrakt		The reconstitution of the history of a fatigue process is based on the knowledge of any correspondences between the morphology of crack surface and the velocity of crack growth (crack growth rate - CGR). The textural fractography is oriented to mezoscopic SEM magnifications (30=500x). lmages contain a complicated texture without distict borders. The aim is to find any characteristics of this texture which correlate with CGR. Pre-processing of images is necessary to obtain a homogeneous texture. Three methods of textural analysis have been developed: method based on the spectral structure of the image, method based on a Gibbs random field (GRF) model, and method based on the idealisation of light objects into a fibre process.
