An improved semi-analytical solution for stress at round-tip notches

Highlights

 

A semi-analytical model is developed for the notch tip maximum stress.

Application of the formula to U and blunt V-notches is demonstrated.

The results can be used to assess the brittle failure of notched components.

notch tip radius

Hello everyone,

 

I am looking for a way to measure notch tip radius experimentally. Would you give me some ideas about that? is there any relationship between  morphology of notched cracked body surface and notch tip radius?

 Thank you and Regards,
