This investigation examines the variation of the fatigue notch factor with notch size for sharp and blunt notches. Analytical expressions are developed to predict the fatigue notch factor for sharp notches based on short crack fracture mechanics and for blunt notches based on Neuber's rule. Experimental evidence to support these expressions is provided together with fatigue notch factors for circularly center-notched plate specimens of 2024-T351 aluminum and SAE 1045 steel. The notch diameters were varied from 0.24 to 5.0 mm. The specimens were tested in laboratory air under uniaxial constant-amplitude loading at load ratios of R = -1 and R = 0. Further experimental evidence to support the analysis is provided by data from the literature for two low carbon steels and a copper. At the fatigue limit, the fatigue notch factor increases with notch size for sharp notches. However, a notch-size effect does not occur for blunt notches. The observed notch-size effects from this and other investigations are in good agreement with the analytical expressions that are presented.

The fatigue-crack propagation at stress concentrations is a topic of significant importance in a number of engineering applications. Further, it is recognized that the fatigue limit of notched components is dictated by the critical condition for either initiation or propagation of a small crack at the root of a notch. Moreover, because most fatigue cracks spend the vast majority of their lives as short cracks, the behavior of such a flaw is of significant importance. In the literature, McEvily and co-workers [McEvily, A. J., Eifler, D., and Macherauch, E., "An analysis of the Fatigue Growth of Short Fatigue Cracks," Eng. Fract. Mech., Vol. 40, No. 3, 1991, pp. 571-584] developed a modified linear elastic fracture mechanics (LEFM) approach to tackle a number of fatigue problems, including the growth and threshold behavior of small fatigue cracks. In this study, a further extension is presented to deal with notch effects in fatigue. In this method, the elastic-plastic behavior and the crack closure are taken into account, as the major factors responsible for the peculiar behavior of small fatigue cracks emanating from notches. In the present paper, the notch effect in fatigue is systematically investigated by making use of a mechanism-based computational framework. A series of parametric studies demonstrate the predictive capability of the proposed framework. Based on the thorough investigation for notch-fatigue problem, the novelty of present study is illustrated.

Nearly 500 years ago, Leonardo da Vinci observed that long wires are weaker than short wires of the same diameter. The statistical theory of extreme values (weakest-link theory) plays a very important role in studies of the size effect; competing theories include the energy theory and the technological theory. Summaries are given of relevant publications identified in the course of a literature survey on the size effect. Since this survey was motivated by concern about the reliability of large composite aircraft structures, which are now coming into use, special attention is given to the size effect on composite materials and structures. An attempt is made to summarize the present state of knowledge and to identify unsolved problems requiring further research.
