Stress intensity factor for 3D crack in ansys

Submitted by kirthanlj on

Hello to all the research scholars. Sir, I am a Phd student in computational fracture mechanics. Right now i am stuck with a problem where i am not able analyze SIF (K1, K2, K3) for a 3D crack in ansys. Ansys asks the path for K value and i am choosing 5 nodes along the 2 crack edges for a full crack model and I also went for both global coordinate system and local coordinate system for finding K. Finally when i went to nodal calc and SIF then it is giving only plane stress and plane strain conditions with full or half crack models. But I am not able to get SIF on the crack front as i am not choosing the path along the crack front. It is only giving SIF at the crack tip considering only the area. Am i not correct or does ansys has limitations on this. Please guide me in this.

Best regards

Dear all

I am also facing same problem, to simulate crack growth in 3D model in ANSYS.

If any one has any suggestions or tutorial please send me at following id:-
