Abstract

In this project a contribution to guarantee the safety of structural parts of steel against brittle failure should be made with the application of Eurocode 3 and other fracture mechanics failure concepts. The assessment of the transferability of parameters from Charpy impact test and fracture mechanics test was given prominence. The intention was to show that the inexpensive Charpy impact test with its little expenditure is able to assess material toughness with fracture mechanics criteria. A number of steels with yield strengths in the range of 270 to 800 MPa have been examined in a complete temperature series. For the examination of the validity of the safety concepts modern steels like thermomechanical treated steel, high-strength and high-toughness steel were tested among conventional structural steels. The verification of the safety concept Eurocode 3 and its basis the procedure of CEGB-R6 and the Sanz correlation with testing data from fracture mechanics tests has shown different results. The assessment of the fracture behaviour with the CEGB-R6 was quite good. The calculated minimum temperatures of the Sanz correlation and the Eurocode 3 for the most part appear non-conservative with great discrepancies for the tested steels.
