Yu Mao-Hong (Chinese: 俞茂宏, 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.[1][2][3][4] His unified strength theory (UST) has found acceptance as generalized classical strength theory.[5][6] 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[7] regular dodecagon in the π-plane as approximation of the von Mises yield criterion, and
- the Schmidt-Ishlinsky[8][9] yield criterion
and three one-parameter (in addition to the equivalent stress ) criteria: the Mohr–Coulomb theory (Single-Shear-Theory (SST)), the Sdobyrev[10] (Pisarenko-Lebedev)[11][12] 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).
