Abstract / Description of output

High strength steels such as S 690, have become an increasingly preferred solution in construction of offshore platforms and jack up rigs where high strength-to-weight ratio is essential. These structure often employe eements which can have thickness up to 220mm. The conventional approach to material characterization is to perform fracture toughness tests of full thickness specimens, but such large specimens impose practical challenges for testing. In this paper, the current techniques used for fracture toughness estimation of Kmat for full sized specimen are validated against the thickness effect for S 690, characterised at -20oC. The results show that as well as adjusting for the different constraint in a thicker specimen, the effect of microstructural validation across a thick plate also plays a role in determining the fracture toughness.
