Title

Material Model of Case-Hardened Steels for Turbo Gear Applications

Concept

The objective of this joint effort between WZL of RWTH Aachen and Leibniz-IWT Bremen is to allow the extension of a fail-safe calculation of material life for future case-hardening steels considering the VHCF regime, which is indispensable for the new generation of epicyclic gear applications. To achieve this top-level objective, several sub-objectives have to be completed such as:

a) Develop fast rotating recirculating sub-element test rig for determining tooth root bending strength under reverse bending conditions;
b) Gain material data for two new case hardening steel developments in the VHCF-regime;
c) Develop and validate a VHCF material model.
