Abstract
When a fatigue crack approaches perpendicularly to the macroscopically planar interface of an Al2124/Al2124+35%SiC(3 μm) bimaterial, the fatigue crack growth resistance is affected by the elastic–plastic mismatch, thermal residual stresses and the direction of crack approach to the interface. The main purpose of this work is to compare experimental and predicted behaviour to evaluate how such parameters affect the fatigue crack growth resistance in an Al2124/Al2124+35%SiC(3 μm) bimaterial. Results show that the effective stress ratio method (R′) alone cannot predict the fatigue crack growth resistance of such bimaterials accurately and the effects of the elastic-plastic mismatch must therefore be taken into account.
