ժҪ In this paper, a new linear yield criterion expressed by the geometric midline of error triangle between Tresca and Twin shear stress yield loci on the ��-plane in Haigh-Westergaard space is introduced. The criterion is written in terms of the principal values of stress deviator and called GM yield criterion for short.
