Description:

The contribution deals with finite element analysis of stress state in sub-sized pre-cracked three-point bend specimen (KLST). A studied material was Eurofer ‘97 steel. The true stress-true strain curve was obtained from tensile test. 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 of standard fracture toughness determination because loss of crack-tip and out-of-plane constraint. and Obsahuje seznam literatury
