Díaz Portugal, Andrés Martínez Pañeda, Emilio Alegre Calderón, Jesús Manuel 2021-03-23T12:54:38Z 2021-03-23T12:54:38Z 2019-02 1350-6307 http://hdl.handle.net/10259/5657 10.1016/j.engfailanal.2018.10.012 In recent years, the pre-notched or pre-cracked small punch test (P-SPT) has been successfully used to estimate the fracture properties of metallic materials for cases in which there is not sufficient material to identify these properties from standard tests, such as CT or SENB specimens. The P-SPT basically consists of deforming a pre-notched miniature specimen, whose edges are firmly gripped by a die, using a high strength punch. The novelty of this paper lies in the estimation of fracture properties using dog-bone-shaped specimens with different confinement levels. With these specimens, three confinement variations have been studied. The results obtained enable the establishment of a variation of fracture properties depending on the level of confinement of each miniature specimen and selection of the most appropriate confinement for this goal.
