M. Benguediab et al., Correlation between crack growth rate and fractography observations in 2024-T351 Aluminum Alloy, AR J SCI EN, 24(2B), 1999, pp. 261-270
The crack propagation behavior in 2024-T351 Aluminium Alloy under constant
amplitude loading has been studied. This study is complemented by crack ope
ning load measurements using a compliance technique and by quantitative mic
rofractographic observations.
The results obtained under constant amplitude fatigue tests show that diffe
rent crack propagation stages can be identified. Significant effects due to
load ratio changes have been quantified. A method for quantitative analysi
s of fatigue surface is proposed.
