Fracture mechanics parameters estimation of CCT specimens made of X 5 CrNi 18 10 steel
This study investigates fracture behaviour of specimens made of high ductile stainless steel. Investigated material was X 5 CrNi 18 10 steel and the specimens used in this investigation were prepared as centre crack tension (CCT) specimens. Pre-cracking of specimens was done by controlled cycling loading. For determination of J-integral, as one of important fracture mechanics parameters, a single specimen method with loading-unloading procedure was used. The same experiment was numerically modelled by using commercial software for finite element analysis – ANSYS. The standard node releasing technique was implemented in finite element method simulation to simulate crack propagation. Numerically obtained results were compared to the results obtained by experiment.
