Advances in Durability Analysis and Maintenance

The next TC24 meeting was held at PoliMi on 1-2 October 2014, at the Department of Mechanical Engineering of Politecnico di Milano.

The opportunity of the meeting is offered by results obtained within EU projects (EURAXLES, SUSTRAIL) and other projects about new concepts for fatigue design and durability, that can represent a significant advance and challenge to currect practices.
Moreover, new interesting outcomes about maintenance and inspections will be presented.

The presentations are available here.
