New rotating bending testing machine expands testing methods under cyclic stress
On 11 December 2024, the newly procured 4-point rotating bending test system Power ROTABEND (100 Nm) from SincoTec Test Systems GmbH was put into operation at the WOT. This expansion of the machinery allows the testing of cyclic load capacity under rotating bending, as is relevant for the use of rotating shafts, for example.
As part of the newly approved joint DFG project „Data-based process property models for the prediction of alternating strength“ with the Chair of Microfabrication Technology (Prof. Andreas Schubert) at Chemnitz University of Technology and the Chair of Scientific Computing and Optimisation (Prof. Roland Herzog) at Heidelberg University, funding has been successfully acquired for a rotating bending test system.
Following the successful kick-off meeting with all project partners on 6 December 2024, the rotating bending testing machine required for the project has now also moved into the WOT. The inhomogeneous stress distribution due to the rotating bending load reinforces the supporting effect of the material's microstructure so that microscale influencing factors on the fatigue strength can be specifically investigated. This makes it easier to separate the effects compared to cyclic testing under axial load.
The Department of Metallic Materials and Material Fatigue is therefore delighted to be able to work with this machine in the future, and the focus of further investigations will be on the cyclic load capacity of the novel material and coating systems developed at the professorship.
The rotating bending testing machine is funded by the German Research Foundation (DFG) - project number 547640565.
