Yu Mao-Hong

Yu Mao-Hong (, b. 1934) is a Chinese engineer and a university professor. He is noted for his research on the strength criteria and yield surfaces of isotropic materials. His unified strength theory (UST) has found acceptance as generalized classical strength theory. It contains the following strength theories (hypotheses) and criteria as a function of the equivalent stress without any additional parameters:

• the normal stress theory (the William John Macquorn Rankine hypothesis),
• the Tresca yield criterion,
• the Sokolovsky regular dodecagon in the π-plane as approximation of the von Mises yield criterion, and
• the Schmidt-Ishlinsky yield criterion

and three one-parameter (in addition to the equivalent stress ) criteria: the Mohr–Coulomb theory (Single-Shear-Theory (SST)), the Sdobyrev (Pisarenko-Lebedev) criterion, and the Twin-Shear-Theory (TST). The Unified Yield Criterion (UYC) as a part of the UST is used in the theory of plasticity (physics).
