As far as I know, there is a formula (Bridgman) for the calculation of stress triaxiality for a sample having a notch on either side or for a flat grooved sample.

Now my question is, if I have a sample just having a single notch on one side can I use the Bridgman formula?

  • There are analytical expressions. See https://core.ac.uk/download/pdf/4385492.pdf, Section 6.1.1.3. – Biswajit Banerjee Apr 24 '21 at 21:17
  • @BiswajitBanerjee So many thanks for your attention and response, but in Fig.6.1, it was shown that the shape of the sample is in the flat-grooved plate. And both sides of the sample have a notch, while my sample has just one notch. – Zolo Apr 25 '21 at 16:28
  • You will need to go to the cited literature to find your case. It exists, as far as I know. However, I'm not affiliated with a university and don't have access to scientific journal literature. – Biswajit Banerjee Apr 25 '21 at 21:20
  • I looked at the reference, but it was not what I have searched for. Thnx – Zolo May 05 '21 at 08:54
