What is Surface Undulation Effects on ER70S-6 Fatigue about?

This article investigates the impact of surface undulations on the fatigue behavior of wire arc additively manufactured (WAAM) ER70S-6 steel through numerical and analytical models. It presents two simplified analytical models to predict local stresses in WAAM material, demonstrating their accuracy in predicting fatigue life and crack initiation. The study highlights the significance of surface irregularities caused by the manufacturing process and proposes fatigue design classes based on the findings.
