Modeling of a creep process between rough surfaces under tangential loading
Source abstract
Abstract
If two bodies with rough surfaces are brought into contact and an increasing tangential load is applied, there will be some relative tangential displacement of the bodies due to the contact stiffness and partial slip in the contact area. The sliding areas will increase with increasing load until the condition of complete sliding is fulfilled and macroscopic sliding starts. In this paper it is suggested that an essential part of the slow creep observed in many contact problems is due to this combined effect of elasticity and partial slip. To prove this hypothesis, tangential creep in contact of rough surfaces is simulated using the assumption of a constant coefficient of friction. The results of the simulation are compared with high resolution experimental measurements of creep between steel samples. In the most cases, the surface parameters can be adjusted to achieve a good description of the experimental data.
