Fatigue Crack Growth Data for U75V Rail Steel Xianfeng Wang (24557550) Metals and alloy materials Civil engineering not elsewhere classified Solid mechanics Theoretical and applied mechanics fatigue crack propagation rate crack growth mechanism rail steel <p dir="ltr">This dataset contains fatigue crack growth data from six compact-tension specimens extracted from the rail head of U75V steel. Tests were conducted at a stress ratio of 0.1 and a loading frequency of 10 Hz, with maximum applied loads ranging from 11.7 to 15.2 kN. Crack length histories were determined using the compliance method and used to calculate crack growth rates and nominal stress-intensity-factor ranges. The data support the analysis of specimen-to-specimen variability, the construction of nominal and minimum-shielding master curves, and the characterization of equivalent crack-tip shielding evolution.</p> 2026-09-18T17:14:12Z Dataset Dataset 10.6084/m9.figshare.33937138.v1 https://figshare.com/articles/dataset/Fatigue_Crack_Growth_Data_for_U75V_Rail_Steel/33937138 CC BY 4.0
