“…It has been shown that it is possible to model the surface evolution of deterministically structured bar stock with a tribological system consisting of zinc phosphate (ZnP), sodium soap and oil in a laboratory environment [15]. Within this current study, it will be shown that the developed surface evolution model is also applicable to nondeterministically structured surfaces with state-of-the-art multiple layer lubrication systems.…”

“…In contrast to Stahlmann et al's implementation [15], the surface data were not stored in an additional background mesh, e.g., matrix. Within Simufact, it is possible to store user-defined data (up to 20 data sets) alongside other nodal data (such as coordinates or contact stress).…”

“…This results in less of an information loss, since the surface data is only remeshed and mapped during global remeshings, while the data stored on a background mesh are mapped at every increment step. For further details, see [15].…”

“…Recently, Stahlmann et al [15] presented a phenomenological model to describe the surface evolution for cold forming processes. With the help of sliding compression tests (SCT), the surface evolution of the specimens was determined and the necessary model parameters were thus obtained.…”

Lubricants for cold forging operations do not only enable a reliable forging process, but also affect the results of forging processes. A sound lubrication decreases the occurring forces and may result in a smooth specimen surface. However, some lubricants are known to increase the initial surface roughness of the specimen as a consequence of the forming. Therefore, the decision which lubricant should be used is of special interest for near-net shape operations. The paper at hand presents the results of a finite element investigation of the first stage of an industrial rod extrusion process which was investigated with two different lubrication systems. The numerical investigations focus on a reliable prediction of the development of the surface roughness in due consideration of the lubricant.

Dynamic evolution of interface roughness during friction and wear processes

This is the pre-peer reviewed version of the following article: Kubiak K.J., Bigerelle M., Mathia T.G., Dubois A., Dubar L., Dynamic evolution of interface roughness during friction and wear processes. Scanning Vol 36 (2014) After an initial period of rapid degradation, dynamic evolution of surface roughness converges to certain level specific to a given tribosystem. However, roughness at such dynamic interface is still increasing and analysis of initial roughness influence revealed that to certain extent, a rheology effect of interface can be observed and dynamic evolution of roughness will depend on initial condition and history of interface roughness evolution. Multiscale analysis shows that morphology created in wear process is composed from nano, micro and macro scale roughness. Therefore, mechanical parts working under very severe contact conditions, like rotor/blade contact, screws, clutch etc. with poor initial surface finishing are susceptible to have much shorter lifetime than a quality finished parts.
