The greatest divergence in predicting the yield stress for distortion between the Tresca’s criteria and Von-Mises criteria occurs at __________

The greatest divergence in predicting the yield stress for distortion between the Tresca’s criteria and Von-Mises criteria occurs at __________ Correct Answer pure shear stress

The following diagram represents both the Tresca’s and von-mises criteria for yielding. For the uniaxial tension/compression and balanced biaxial stress, the yield stress for both the cases are the same. In the case of pure shear σ1=-σ3 (shown by the yellow line) shows the maximum deviation in predicted yield stress values.
