All materials are concerned.

The main objective is to understand the impact of a given defect population on the fatigue behavior

- from a material optimization point of view (i.e. the link with the material elaboration and manufacturing process) and also

- from a design optimization perspective (i.e. definition of an allowable defect size).

 

Topics for abstract submission include:

• Material defects and manufacturing processes.
• Statistical distribution of defects.
• In-service defects:  scratches, wear, Foreign Object Damage (FOD)...
• New experimental techniques (nondestructive defect characterization, crack initiation detection, crack propagation monitoring, etc)
• Short crack effects
• Stress concentration effects
• Multiaxial stress effects
• Fatigue limit modeling including defects
• Fatigue life modeling including defects
• Through Process Modeling (Fatigue modeling taking into account the manufacturing process)
• Defect size mapping on structure for engineering design.
