- The moving plate in this model made the ball roll by the friction between the ball and the plate. And the contact stress, the contact strain and the friction stress of this model were analyzed in this paper. 并建立了平板-球体接触模型,以平板的摩擦驱动与之接触的球体,得出了运动条件下模型的接触应力、应变以及摩擦力的分布。
- The results indicated that the crack was caused by the mutual actions both surface shear friction stress and distorting stress, and the cracks developed in the way of stress corrosion. 结果表明：上轴裂纹是在较大的表面剪切摩擦应力与扭转应力的共同作用下发生的开裂，裂纹开裂后以应力腐蚀的方式扩展。
- The friction stress between the tool and the chip is assumed to follow a modified coulomb friction law and the local adaptive remeshing technique is used for the formation of chip. 切屑和刀具的摩擦应力采用修正库仑摩擦方程来计算,工件的流动应力是应力、应变、应变率和温度的函数,采用局部网格重划分技术。
