- •
Nominal stresses should not be assumed as purely elastic in notch concentration rules.
- •
Notch formulations considering elastoplastic nominal stresses are presented.
- •
Neuber’s and Glinka’s rules are evaluated based on Finite Element analyses.
- •
Glinka’s yields better predictions than Neuber’s rule under plane stress conditions.
- •
3D notch effects can be significant when dealing with thick specimens.
