✦ Synopsis
A B S T R A C T Fatigue tests with sharply notched compact tension (CT) specimens of 7075-T6 aluminum were conducted for constant ratios of R = amen~area ~ and constant notch root radius, p. By monitoring the crack propagation throughout the tests, the number of cycles at which the characteristic state of stress near the notch root has no further influence on crack tip velocity could be determined. The results are discussed on the basis of Neuber's theory of macro-support effect. An analogy to linear elastic fracture mechanics is pointed out.
