Dear All,
I am currently performing an ECA (Level 2) based on BS7910 for a welded component. The material is equivalent to API 5LX65. I have not performed CTODs to obtain δmet, instead I have used Charpy v notch values to obtain Kmet values based requirement on Annex J of BS7910.
I understand that both are based on different assessment routes, one being strain based and the other stress based. My dilemma is that my ECA program which I have developed is based on CTODs as a main input criteria, and it will take a lot of effort to adjust the calculations accordingly.
My question is; is there a method/equation I can use to convert Kmet to δmet without performing additional CTOD tests.
Kind regards
