4. Conclusion

The discrepancy between expected and obtained  xx values might be related with additional stress introduced during drilling process as well as residual stress from material processing. Further tests are planned to be made on annealed samples to verify this hypothesis. Additionally, comparative tests with tensometric rosettes are also planned to be made.
