Crack Propagation of Aluminum Alloy 2024 T351 under Constant Amplitude Loading Using Crack Closure Concept

Abstract:

The crack propagation behavior in a 2024 T351 Aluminum Alloy under constant amplitude loading has been studied. This study is analyzed in term of crack opening load measurements using a compliance technique. The results obtained under constant amplitude fatigue tests show that different crack propagation stages can be identified. Significant effects due to load ratio changes have been quantified.
