Experimental verification of thickness effect on fatigue crack growth in AA 2124 plate
Original language description
Both predictions and experimental results indicate for some materials significant discrepancies between crack propagation data of machined parts from a thick plate to different thinner thicknesses. The different fatigue crack growth behavior under constant and variable amplitude loading can be recognized. The thickness influence could be one of the main possible reasons for this unexpected behavior. The paper deals with a plate thickness of 50 mm made from 2124 T851 aluminum alloy. Crack propagation was investigated for various specimen thicknesses and different loading conditions. No significant thickness influence on the crack propagation behavior occurred both for constant and variable amplitude loading typical for a commuter aircraft loading spectra. It implies that present prediction models are able to predict the crack propagation in this material only using basic material characteristics defined under the constant amplitude loading.
