- •
Stress concentration effects depend on the notch tip profile.
- •
Circular arcs are not the best notch tip shapes.
- •
Notch tips with proper variable radii can significantly decrease stress concentration effects.
- •
Simple optimization schemes are proposed to optimize notches loaded by uniaxial and multiaxial loads.
- •
Optimized shapes are proposed for several fatigue test specimens.
