Then the shift stresses were analyzed to specify the yield locus in true stress space and rotational hardening law was adopted to embody the anisotropy induced by stresses.
分析迁移应力，确定了真实应力空间中的屈服函数，并采用旋转硬化规律考虑应力引起的土体各向异性。
2
The max stress and the max radial displacement of conveyor is also proportional to the square of rotational speed.
螺旋输送器的最大应力强度和最大径向位移均与转速近似地成二次方关系；
3
At the same time, the influence laws of the rotational speed and suspended stretch of the tools on the radial displacement and the maximum equivalent stress have been investigated in detail.
