when using DDT with non-uniform traction on the crack-face, we can get stress intensity factor (K), through numerical computation . The computed K for each track tip is different (in general) and obtained from the distributed dislocations on the crack face using Krenk's formula.
Is there a difference between nature of stress field of such singularity and the conventional crack with uniform traction, where square-root singularity is well-established?
