WCFA'24 - Fatigue Crack Growth
Programme of the Workshop
In previous volumes of the WCFA workshop, we usually dedicated the first day to onboarding newcomers - engineers who were not educated in fatigue analysis or who had forgotten everything while practicing in other engineering domains. We decided to skip this one-day course this year to make the rest of the lectures over 2.5 days more manageable. If you miss the introductory course Introduction to Fatigue, it can be accessed online from previous recordings, either from the Vibration Fatigue Analysis workshop in 2022 or the FKM-Guideline Non-Linear workshop in 2023.
To better meet the needs of participants and their level of fatigue knowledge, several variants of the course are provided:
| Wednesday December 4, 2024 (6 hours of lectures) |
D. Quaranta: Damage Tolerance, Fracture Mechanics and Crack Growth in Aerospace Industry | V1 | V3 |
| Thursday December 5, 2024 (6 hours of lectures) |
K. Rother: FKM Guideline on Fracture Mechanics | V2 | |
| Friday December 6, 2024 (3 hours of lectures) |
K. Rother: FKM Guideline on Fracture Mechanics |
Topics discussed in individual days follow.
