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。

The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。
