Fatigue failure model with peridynamic theory
WebJun 1, 2024 · Based on the peridynamic fatigue theory and considering the supporting effect of sleepers on the rail and the moving effect of the wheel load, this study proposed a 2D prediction model for the fatigue crack initiation of railheads. First, the parameters of the analysis model are reasonably valued.
