Resumo
This work presents procedures for experimental estimation of J - integral and CTOD (d) using the eta (h) method and SE(T) specimens in clamped and pin-loaded conditions. Homogeneous materials and also specimens containing mismatched welded joints are considered. The conceptual background is presented, followed by the details of the various finite element models developed for the analyses. As results, are presented h factors for J and CTOD experimental estimation. The main objective is to allow fracture toughness experimental evaluation using SE(T) specimens to reduce the conservatism in integrity assessments of pipelines and pressure vessels, which present very similar fracture conditions. Consequently, the results contribute for a better understanding of SE(T) specimens and encourage further developments since they are not available in current standards.
