The project:
The load-carrying capacity of widely used case-hardened gears in wind turbines is limited by tooth flank fracture, which occurs as a result of cracks initiated in the component’s depth due to unfavorable residual stress state induced by the heat-treatment. A reliable prediction model for tooth flank fracture relying on a good description of the residual stress state after case-hardening heat-treatments is to be developed.

Tasks:
Based on an existing Finite Element model for the heat-treatment, the candidate will identify relevant methods and boundary conditions to link the residual stress simulation results to an assessment of the tooth flank fracture risks in a FE tool. Literature survey, building up the model and applying it through parameter studies will form the thesis’ core, while further developments with consideration of the effects of non-metallic inclusions are possible.

Requirements:
– Knowledge in materials science or steels
– Interest in numerical simulation
– Motivation and reliability
– Ideally experience with Abaqus and Matlab or Python

We offer:
A comprehensive and industry-relevant thesis in line with the latest state of this research field. The candidate will be will be part of a pleasant working environment and helpful team.
