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 hypotheses 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 nonparametric strength theories and criteria:
- the normal stress theory (the William John Macquorn Rankine hypothesis),
- the Tresca yield criterion,
- the von Mises yield criterion (the Sokolovsky[7] regular dodecagon in the π-plane), and
- the Schmidt-Ishlinsky[8][9] yield criterion
and three one-parameter 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).
