A reliable local-fatigue assessment approach for rotary friction-welded components does not yet exist. The scope of this paper is to present test results for the fatigue behaviour of rotary friction-welded solid shafts made of structural steel S355J2

The determinination of material properties is an essential step in the simulation of manufacturing processes. For hot deformation processes, consistently assessed Carreau fluid constitutive model derived in prior works by Schmicker et al. might be us

In order to reduce the deficits in single-sided resistance welding (SSSW), single-sided resistance brazing represents a perspective alternative. Due to the reduced thermal and mechanical damage, the dynamic load capacity of the component increases. B

For the numerical simulation of the rotary friction welding process in prior works a modified Carreau fluid law has been successfully adopted, which can so far not be used for the residual stress prediction due to the basic assumptions in this model.

Journal bearings are still widely used, and – in combination with the omnipresent trend of light weight construction – there is an increasing focus on transient behaviour. Therefore, the structure, or more precisely, the aspect of rotordynamics h

In order to reduce the deficits in single-sided resistance welding (SSSW), single-sided resistance brazing is a promising alternative. The reason for this is a process-related reduced thermal and mechanical component impact compared to SSSW. In the u

The simulation of Rotary Friction Welding (RFW) is a challenging task, since it states a coupled problem of phenomena like large plastic deformations, heat flux, contact and friction. In particular the mesh generation and its restoration when using a

The subject of this paper is the presentation of a holistic, fully-temperature-coupled simulation of Direct Drive Friction Welding (DDFW) based on the modified Carreau fluid model. The main motivation therein is the consistent and stable prediction o
