J. Cent. South Univ. Technol. (2011) 18: 1018-1023 DOI: 10.1007/s11771-011-0797-0 Analysis of complete plasticity assumption for solid circular shaft under pure torsion and calculation of shear...-section. The distribution of shear stress is still linear with the maximum shear stress τs. The complete plasticity model assumption is not in accordance with the actual situation of shaft under torsion......
