Yu Mao-Hong

Prof. Yu Mao-Hong (2015)

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 models: 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).
