Fracture Toughness Data
Fracture Toughness Data
(OP)
Is there anywhere on the web where I can find Fracture Toughness data for pressure vessel steels such as BS EN10028 P355, or structural steels such as BS EN10025 S275 Etc?
We have been carrying out some fracture mechanics work based on Charpy values, and have been asked not to use the
correlation between Charpy and Fracture toughness, but used some realistic fracture toughness values instead....and I'd rather not pay for testwork to be carried out, if the data was readily available.

My suggestion would be to find an appropriate test house that will do the work for you (there are several in the UK that do good quality FT testing - I'd be happy to provide suggestions outside of the forum). If you really want to go down the literature route, then the best source of information on steels of various compositions that I know of is shown below. ESDU is a great source of data and engineering methods, but you need a subscription to use it. (I am not associated with it other than as a user.)
Finally, you could possibly reduce the amount of testing by doing a smaller amount of testing and using the ESDU values in combination.

Data Item 83023
Fracture toughness (KIc) values of some steels.
Shortened Abstract: ESDU 83023 provides more than 1750 plane strain fracture toughness values for 39 UK and US low alloy, nickel, maraging and stainless steels. The data are presented in tabular form, providing details of test temperature, crack orientation with respect to grain flow, proof stress, chemical composition and heat treatment.
