Episode 4 - Mohr's Circle


Talking Shop with Tony Abbey
NAFEMS is talking shop with Tony Abbey on a range of topics relevant to, and suggested by, the engineering analysis community.


Mohr’s circle seems to be a very unpopular topic in structural mechanics courses!

Tony thinks it is because it seems:

  • Very arcane
  • Very procedural
  • Very confusing
  • Never used in practical engineering

Why bother with Principal Stresses, Maximum shears etc. – Von Mises is king!! Maybe don’t want to go back to graphs, but:

Perhaps Mohr’s circle is useful today to help understand:

  • What are stress transformations?
  • Why do them?

Tony's trying to give Mohr a boost here!


This series is available for free to the engineering analysis community, as part of NAFEMS' efforts to bring the community together online.
