	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. Damage Tolerance, Fracture Mechanics and Crack Growth in Aerospace Industry This part is covered in the following variants: Introduction to Fatigue (V1), Complete Course (V3). A more detailed schedule will be provided in September. The standard setup for a lecture da,y as in previous volumes of WCFA, will be followed. Lectures will start at 9:00 AM, so please ensure you register before that time. There will be a 30-minute coffee break, or a 90-minute lunch break every 90 minutes of lectures. The topics covered during this day include: Part 1: Damage Tolerant (DT) design Fatigue Cracks in Metals Fatigue Design Criteria Development from Safe Life to Damage Tolerance DT assessment workflow Differences with respect to the Safe-Life assessment workflow Part 2: Linear Elastic Fracture Mechanics (LEFM) Stress Intensity Factors (SIF) LEFM limits of validity SIFs derivation/calculation methods SIFs from Weight Functions SIFs from FEM Kink Angle Part 3: Crack Growth (CG) Models da/dN models Paris, Walker, Nasgro, tabular lookup) Small cracks CG Life integration algorithm Through cracks in thin structures Cracks in thicks structures Residual strength check and critical crack size Part 4: DT Special Topics Retardation effect Inspection intervals Continuing damage approach Primary and secondary cracks DT design features (crack stoppers) Cold working and interferce fit effects Testing DT designed structures and loads derivation FKM Guideline on Fracture Mechanics A more detailed schedule will be provided in September. This part is included in all variants except for Introduction to Fatigue (V1). It covers the whole day on Thursday December 5 (concluding with the Social Evening) and the morning session of Friday December 6. The same schedule as the previous day will apply - we start at 9.00 AM, each block of lectures lasts 90 minutes, with 30-minute coffee breaks and a 90-minute lunch break. On the final day, to ensure you are not hungry before your departure, the workshop will conclude with lunch. The content of the lectures during these one and half days includes: Introductory remarks Background information and overview of the guideline Basics on fracture mechanical concepts Linear elastic vs. elastic-plastic fracture mechanics Failure assessment diagrams Static vs. cyclic loading Assessment concept of the guideline Input quantities and modelling Defects Stress state Material properties Computational Procedures Static loading Cyclic loading Advanced topics Proof concept Safety margins and reserve factors, sensitivity analysis, probabilistic analysis Applications     Timetables of past volumes WCFA'23 & FKM-NL WCFA'22 & VFA WCFA'19 & PHL WCFA'18 & FKM WCFA'17 & DFW WCFA'16 & VFA WCFA'13 & PUM05 WCFA'11 & PUM04 WCFA'09 & PUM03 WCFA'08 & PUM02 papuga@pragtic.com, last update: November 3, 2024	EXTERN LINKS:
