WCFA'16-VFA
Programme of the Workshop
The course is built in such a way, that no prior knowledge on fatigue analysis is needed. The basic principles of the common fatigue damage estimation are described in the first day, while the content related to fatigue analysis under random loading is extensively discussed in next two days. In order to better suit the needs of participants and to fit it adequately to the level of their knowledge, three variants of the course are provided - Complete Course (for all three days), or Vibration Fatigue (for the second and third days only) and Introduction to Fatigue (for the first day only).
