Displaying yield and failure surfaces

[MCC1966]

Hi
Is there any way where one can display the yield surfaces and/or failure surface.
Thanks

For elastic stresses above yield, just reset the maximum Von Mises contour limit to yield.

If you use an elastic, plasticmaterial, you can use the Flag variable AC YIELD. Since it's a flag you can set the number of colors to two an use a quiltplot in the contour options.
