dc.description.abstractSE(T) specimens are of great interest for the determination of fracture toughness and crack growth resistance of structural steels applied to pipelines and pressurized components, as a result of the similarity between stress fields in the near-tip region, which is not found in conventional C(T) and SE(B) specimens. This work applies the unloading compliance method supported by finite element models for the experimental evaluation of R-curves, using pin-loaded and clamped SE(T) specimens with equivalent crack depths. AISI 1020 steel samples were tested as an example for the experimental methodology. The obtained results allow critical evaluation of load vs. displacement and R-curves, and moreover allow the discussion of the experimental difficulties found in testing both specimen geometries.
