Original Abstract

The contribution deals with finite element analysis of stress state in subsized precracked threepoint bend specimen (KLST). A studied material was Eurofer97 steel. The true stress-true strain curve was obtained from tensile test. The threepoint bend tests were carried out on plain and sidegrooved specimens at ambient temperature and were simulated using ABAQUS 6.10. The stress state in KLST specimen was compared with the stress state of standard specimen. The analysis confirmed the stress state in KLST specimens at the crack tip does not correspond to conditions of standard fracture toughness determination because loss of constraint.
