查询词典 Mises

From FEM, the contact stress obeys the semi-ellipse distribution and the Mises stress and shear stress are also consistent with contact mechanics theory, but there exists offset or deflection in the symmetric lines of stress distribution, which originates from tooth bending deformation.

由有限元方法得到的渐开线轮齿的接触应力符合Hertz理论中的半椭圆分布规律，Mises应力和剪应力分布也符合接触力学理论，但应力分布的对称中心存在偏离或者偏斜现象，分析认为，是由于轮齿弯曲变形造成的。

At the same time, for the polishing plate of diamond film with the same thickness, von Mises equivalent stress and the radial displament show a ascending tendency with the increase of rotating speed, but the axial displacement firstly increases and then decreases.

同时，对于同一厚度的金刚石膜抛光装置，随着转速的提高，von Mises等效应力和径向位移呈现相似的上升趋势，轴向位移却先上升后下降。

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。

In order to deeply reveal the smoothing mechanism of roller burnishing and to overcome the difficulty in the selection of the burnishing cross feed dependent mainly upon experiences and hand feel, the roller burnishing process is taken as an issue of plane-strain mechanics and the micro-plastic deformation area is determined on the basis of the Von-Mises yield criterion and by using the Boussinesq-Flamant solution. Then, the contact pressure distribution is obtained based on the Hertz contact theory, and the stress distributions in the burnishing tool and the workpiece are respectively revealed.

为深入了解滚柱滚压表面光整机理，解决目前滚压量选择完全凭经验和手感的不足，将滚柱滚压加工过程视为平面应变力学情形，利用Boussinesq-Flamant问题的求解并根据Von-Mises屈服准则得出了滚压局部发生微塑性变形的区域，根据Hertz接触理论得出了滚压接触压力分布及滚压过程中工件和工具的应力分布。

The two definitions of dilatancy in slip line theory are clarified, and the generalized Mises yield criterion matching Mohr-Coulomb yield criterion in plane strain condition is put forward where the effect of dilatancy can be considered.

阐明了滑移线场理论中有关剪胀的描述，推导了平面应变条件下考虑剪胀角影响并与Mohr-Coulomb准则精确匹配的广义Mises准则，研究了剪胀对浅基破坏模式的影响。

Von Mises believed markets, like people, needed to be free from government meddling.

Von Mises 认为市场就像人一样需要摆脱政府的干预。

At one point, Hayek's former mentor, Ludwig von Mises, stormed out of a meeting.

有一次，哈耶克以前的导师－Ludwig von Mises－怒气冲冲地离开了会场。

For other cases, the limit loads based on Mises criterion is proposed instead.

其它情况建议使用基于Mises准则的解。

Then the principle equations of streamline in the general von Mises coordinate system are derived for the first time.

在三维流动情形，引入了两个流函数η和ζ，并通过广义von Mises变换，首次导出了坐标系下的三个流线控制方程。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.
