Abstract

At the design stage of engineering structures, the fatigue behaviour is generally not included in the analysis. Shoulder reinforcements may be machined with too small blending radii. Even if fatigue is taken into account, the influence of the environment is almost always ignored. This paper shows that corrosion-fatigue is not an uncommon cause of failure in industry and that it may result in significant damages. The survey of such failures and the observation of the fracture surfaces allow to identify the typical features of this phenomenon.
