Fundamentals of Fatigue and Fracture Mechanics

reportActive / Technical Report | Accession Number: ADA201435 | Open PDF

Abstract:

The basic tenet of LEFM is that the stress intensity factor, K, is the key controlling parameter for fatigue crack growth and fast brittle fracture under monotonic loading. This research program examined whether or not this fundamental assumption formed an effective basis for an engineering technology. And, as needed, suggested directions for an improved technology.
