The Size Effect in Fatigue of Plain and Notched Steel Specimens Loaded under Reversed Direct Stress

Abstract: The fatigue strength under reversed direct stress was ascertained for specimens of various diameters in the range from 0·19 inch to 2·4 inches, the largest diameter being determined by the capacity of the machines available. Two steels were used in this investigation—a 25-ton mild steel and a 65-ton, per cent nickel-chromium steel. The specimens were either plain or notched (transverse hole) and, as far as possible, geometrical similarity was preserved with regard to the transition radii and the diameter of the transverse hole. A few fatigue tests on other types of notch, such as a circumferential V-groove and a shoulder, were also carried out.No intrinsic size effect with either material was observed with the plain specimens.With transverse-hole specimens in mild steel, the fatigue limit was ±8·4 tons per sq. in. for specimens of 0·33 inch diameter, and 6·1 tons per sq. in. for specimens of 1·7 inches diameter, thus showing that an appreciable size effect was present. A similar size effect was found with...

Application of a weakest‐link concept to the fatigue limit of the bearing steel SAE 52100 in a bainitic condition

Abstract: The influence of notches and load conditions on the fatigue limit of the high-strength steel SAE 52100 is investigated. The behaviour can be described quantitatively by a weakest-link concept which describes competitive crack initiation at the surface and at inclusions. This includes the possibility of calculating local and total endurance probabilities depending on the nominal stress amplitude. Crack initiation sites and the fatigue limit can also be predicted. The basic relation between the size distribution of crack-initiating inclusions and the fracture probability was proved for smooth specimens under tension-compression.

From Neuber’s Elementary Volume to Kitagawa and Atzori’s Diagrams: An Interpretation Based on Local Energy

Abstract: Dealing with sharp V-shaped notches, some recent papers have discussed the possibility of using the strain energy averaged over an ad hoc control volume to predict the static strength of material with a brittle or quasi-brittle behavior as well as the fatigue behavior of welded joints. This approach is applied here to components weakened by cracks and blunt V-shaped notches. As a result, Kitagawa and Atzori’s diagrams reported in the literature to summarise fatigue limit of cracked and notched components are immediately derived, leading to a natural transition between the Linear Elastic Fracture Mechanics and the Linear Notch Mechanics.
