Notched specimens are employed and fracture resistance is assessed through a critical value of the notch mouth displacement {\\delta^SPT}. Finite element simulations and interrupted experiments are used to track the evolution of {\\delta^SPT} as a function of the punch displacement. The onset of crack propagation is identified by means of a ductile damage model and the outcome is compared to the crack tip opening displacement estimated from conventional tests at crack ini","authors_text":"Cristina Rodr\\'iguez, Emilio Mart\\'inez-Pa\\~neda, Tom\\'as E.
