Von Mises found that, even though none of the principal stresses exceeds the yield stress of the material, it is possible for yielding to result from the combination of stresses.
If the "Von Mises Stress" exceeds the yield stress, then the material is considered to be at the failure condition.

This model of material does not take into account reduction of stresses in the tensile zone of the concrete in case of crack opening, because it does not include the descending branch of the σi – εi diagram.
