Fractographie - Bases physiques
Étude et propriétés des métaux, 2002Un organe mecanique est un element destine au fonctionnement d’un ensemble machine ou d’une structure metallique, chaque element ayant une fonction determinee, en parallele ou en serie, avec d’autres organes. Sa conception entraine sa fabrication : elaboration du materiau, transformation (mise en forme a chaud ou a froid), traitement en volume ou en ...

Volume 12 covers all aspects of fractography relevant to its use in materials evaluation, failure analysis, and quality control. In addition to an extensive collection of fractographs, it includes information on the types and appearances of fracture, visual examination and imaging methods, quantitative fractography, surface profiling, and fractal ...

This paper discusses the applications and the limitations of the fractography technique as applied to the fiberglass industry. The main limitation of fractography originates from the fact that fibers of strength greater than about 2000 MPa shatter into multiple small fragments upon fracture rendering it impossible to capture the true fracture surfaces.

Abstract This article provides an overview of polymer fractography, with examples of various fracture surfaces created under diverse loading conditions. The focus is on the interpretation of polymer fracture-surface features in light of the unique viscoelastic nature of polymers.
