How to cut a surface in ANSYS workbench?

Click For Summary
SUMMARY

To analyze a fracture in a surface body using ANSYS Workbench, it is essential to create a no thickness or infinitesimally small cut. This approach allows for the evaluation of stress concentration factors within the model environment. While modeling a cut or crack that is small relative to the overall model is a common method, it is crucial to note that crack analysis in ANSYS is a well-established field with extensive literature available for reference.

PREREQUISITES
  • Familiarity with ANSYS Workbench for finite element analysis
  • Understanding of fracture mechanics principles
  • Knowledge of stress concentration factors
  • Ability to interpret engineering research papers on crack analysis
NEXT STEPS
  • Research methods for creating infinitesimally small cuts in ANSYS Workbench
  • Learn about fracture mechanics and its application in ANSYS
  • Study the evaluation of stress concentration factors in finite element models
  • Review relevant literature on crack analysis techniques in ANSYS
USEFUL FOR

Engineers, researchers, and analysts involved in fracture mechanics, particularly those utilizing ANSYS Workbench for stress analysis and crack modeling.

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?
