An Efficient Criterion for Evaluating Fatigue Strength Improvement Through the Stop-Hole Technique
This study investigates the effect of a non-zero fillet radius, <i>ρ</i>, on the fatigue behaviour of notched components under uniaxial loading. A new diagram is introduced, which discusses the relationship between the notch tip radius and the fatigue limit. It also identifies a critical...

| description | This study investigates the effect of a non-zero fillet radius, <i>ρ</i>, on the fatigue behaviour of notched components under uniaxial loading. A new diagram is introduced, which discusses the relationship between the notch tip radius and the fatigue limit. It also identifies a critical radius, <i>ρ</i>**, precisely marking the transition from sharp to blunt notch behaviour. Additionally, its application to the “stop-hole” technique is considered, where both material properties and geometric characteristics are analysed, demonstrating that introducing a fillet radius can improve fatigue resistance. |
