Data analysis of striation spacing, lifetime, and crack length in crankshaft ductile cast iron under cyclic bending loading through high-cycle fatigue regime.

ABSTRACT: In this dataset, experimental results of high-cycle bending fatigue testing on crankshaft ductile cast irons were presented both in raw and analyzed data. For this objective, EN-GJS-700-2 standard samples were cut and machined from the crankshaft of a gasoline engine. Then, stress-controlled rotary fatigue experiments were done on cast iron specimens under cyclic four-point bending loads in a fully-reversed condition (zero mean stress). These tests were considered under different cases of the loading rate and the applied stress, for both smooth and notched samples. The loading frequency was set to 12.5, 33.3, 58.3, and 100.0 Hz. The nominal stress was 226.6, 340.0, and 415.5 MPa in unnotched specimens. These values became 310.9, 513.6, and 642.4 MPa, respectively, when a notch was made on
