Abstract : In recent years the concept of Damage Tolerance for Aircraft Structures has become widely accepted in the aerospace industry. For the application of this concept, knowledge of crack growth rates has become of primary importance. This meeting brought together specialists in the field of fracture surface analysis and structural test engineering with the aims of: reviewing available methods for determining the growth of cracks from their topography - noting any shortcomings in these methods and recommending further research and development. The four sessions of the meeting were devoted to 'Phenomenological Aspects of Fatigue Fractures', 'Method and Means of Crack Front Making', 'Fracture Surface Analysis Techniques', and to a general discussion. Originator-supplied keywords include: Airframes, Crack propagation, Cracking(fracturing), Fatigue(Materials), Tolerance(Materials), Surface defects.
