Concrete Stress Analysis

[MacGruber22]

A presenter at the SEI Structures Congress this year spoke about FEM analysis of spherically-voided cast-in-place concrete slabs. He mentioned that he used the Von Mises criterion for checking stress combinations for the concrete. I learned in mechanics that the Von Mises criterion was for ductile materials. Thoughts?

This topic has been discussed here previously and so some searching should bring up several opinions. Von Mises as a criteria is used for ductile materials and those that have equal failure in tension as in compression.
