Research Theme

Fretting Fatigue of Shaft-Hub Connections

Brief Explanation

Fretting corrosion is the most important failure mechanism of form-fitted polygon-shaft-hub connections. Current life prediction techniques need to know the point of crack initiation to obtain the stress and strain distribution. Unfortunately a reliable procedure for the fully-automatic identification of the crack initiation point does not exist. In this study, based on a 3D FEA different damage criteria will be applied to examine the potential of the critical plane method.

Research Steps

1. Literature survey (one month)

2. Practice in FEA (one month)

3. Implementing and testing of an evaluation program for FE-results (one month)

4. Application of several damage parameter to the FE-results (one month)

5. Verification of the prediction reliability (one month)

Period

5 months.

Necessary Background, Knowledge, Skills

Fundamental knowledge about mechanics, stress & strain, fatigue.

Computer programming skills, preferably basics in FEA

If necessary, some references can be specified.
