      Dear all,

      I hope I am not disturbing you. I am modelling a semielliptical surface crack in 3D in ANSYS APDL (but I think it is the same in Workbench). I use singular elements SOLID186 near the crack tip:

      The crack tip node component should include all node along the crack front. Why are you choosing just one node?
      Regards Ishan.

      Dear @1shan thank you for your answer. I have chosen all node along the crack front and this is the reason why I can't find the explanation for the J-Integral oscillations.
      Thank you for your help.
