The influence of plasticity index in mechanical seal application

When the plasticity index is less than 0.6, it is elastic contact; at that time, there is plastic deformation in some areas. In most cases, the plasticity index will exceed 1, because the higher asperity on the surface has a smaller radius of curvature, and plastic deformation will occur even when the contact load is extremely small, while the lower contact asperity is still at In a state of elastic deformation. Therefore, most of the contact is a mixed state of elastoplastic deformation. The greater the load, the greater the proximity of the contact surface and the greater the number of plastic contact points.　　347.html,
