Abstract
Reinforcement of silicon carbide whiskers improved significantly the elastic and strength behaviours of aluminium alloys. Unfortunately, the increase of the volume fraction of whiskers is responsible for a very low ductility of these M.M.C. and the sensitivity to stress concentration is very high. In order to use these materials in some structural components, we need to obtain a fracture criterion for the 2124 Al + 20% SiCw at room and high temperatures (i.e.20°C to 350°C). After a tension and fatigue crack growth characterization, a damage micromechanics modelisation based on the microstructural characteristics such as the aspect ratio and the volume fraction distributions is established.
