A studied material was Eurofer97 steel. The three-point-bend tests were carried out on pre-cracked plain and side-grooved specimens at ambient temperature. Performed tests were simulated using FEA software Abaqus 6.10. The stress state in KLST specimen was compared with the stress state of pre-cracked Charpy and 1T SENB. The analysis confirmed the stress state in KLST specimens at the crack tip does not correspond to the stress state of standard fracture toughness determination because loss of crack-tip and out-of-plane constraint.
