How to cut a surface in ANSYS workbench?

[Butters]

This is more complicated than it sounds. I'd like to analyse a fracture in a surface body so I need to create a no thickness or infinitesimally small cut/slice if it is possible.
Afterwards, I'm planing to analyse stress concentration factor in model environment.

There are a couple of ways you could approach this, the most obvious being to model a cut/crack which is "small" with respect to the overall model but not "infinitely" small. Crack analysis in ANSYS is a pretty well-defined field, there are lots of papers written about it. Have you done any online searches?
