Resumen:
The standards for characterization of fracture toughness of metals are focused on the calculation of fracture parameters based only on in-plane displacements of the specimen tested.Although fracture is a three-dimensional problem, out-of-plane displacements of the specimen tested are not mentioned in those documents. Since three-dimensional displacement measurement isavailable, it is worth investigating its potential uses in fracture tests.In this work, fracture toughness of a structural steel was assessed through standard tests, measuring three-dimensional surface displacements. Initiation of stable crack growth was inferred from out-of-plane displacements, finding good agreement with results from R-curves. Consequently, a novel method for fracture toughness determination was proposed.
