Fatigue stress concentration factor is the ratio of:
1
\(\rm \frac{Endurance\ limit\ with\ stress\ concentration}{Endurance\ limit\ without\ stress\ concentration}\)
2
\(\rm \frac{Endurance\ limit\ without\ stress\ concentration}{Endurance\ limit\ with\ stress\ concentration}\)
3
\(\rm \frac{Theoretical\ stress\ concentration\ factor\ for\ torsional\ or\ shear\ loading}{Theoretical\ stress\ concentration\ factor\ for\ axial\ or\ bending\ loading}\)
4
\(\rm \frac{Theoretical\ stress\ concentration\ factor\ for\ axial\ or\ bending\ loading}{Theoretical\ stress\ concentration\ factor\ for\ torsional\ or\ shear\ loading}\)
