Prediction of microstructure and constraint effects on fatigue behaviour in engineering applications

Ziel

The proposal aims to develop an experimental and methodological know-how to establish the relationship between steel microstructure and constraint effects and fatigue behaviour of high strength structural steels for mechanical components in terms of crack initiation/propagation phase.

The developed know-how will be extended to real in-service conditions and identified engineering applications and components, in particular when multi-axial random loads with overloads are Present.

A validated criterion to predict the in-service behaviour of selected mechanical components, taking account of steel microstructure, surface roughness as well as stress-strain field, will be developed starting from state-of-the-art theories (e.g. Dang Van, Kitagawa-Takahashi, Murakami) and metallurgical knowledge.

Mechanical components production and special testing on full-scale components will be also performed. With these aims a Consortium among CSM, SIDENOR, CEIT, ASCOMETAL and IVECO has been formed.
