Fatigue life evaluation of high-strength steel wires with multiple corrosion pits based on the TCD

The stay cable composed of high-strength steel wires is susceptible to external corrosion during service, and multiple pitting damage will occur on the surface of steel wires. For the sake of simplifying the pitting morphology, this paper used artificial notches to simulate corrosion pits, and the fatigue properties of high-strength steel wires with multiple notches were systematically studied. First, fatigue tests of steel wires with multiple...
