VHCF material model for case hardened gear steels for application in an epicyclic power gearbox

The projects aims to develop a material model for future gear steels considering representative conditions of an epicyclic gearbox such as material volume, stress ratio (R = -1), cycle waveform and dynamic effects but also the relevant very high cycle fatigue regime (VHCF) ≥ 108 cycles. A fast rotating recirculating gear sub-element test rig shall be developed and utilised to generate necessary bending and contact fatigue datasets. Please refer to the full topic descriptions document published in this call.
