Abstract
Adhesively bonded shrink cylindrical joints show good fatigue strength behavior. They have various advantages compared to many conventional shaft hub joints. In drive systems they are often loaded by rotating bending and torsional load. The paper reports on results of tests with rotating bending and oscillating torsional load. The typical failure of the joint for high number of cycles is fretting fatigue. The SN curve of the bending stress (torsional stress as a parameter) decreases rapidly compared to the SN curve for pure torsional loading. The analysis of the available test data leads to the conclusion that the effective stress can be expressed as a linear relation of the bending and the torsional stress amplitude.
