Abstract

A new approach is explored to predict the fatigue life of 2024-T42 aluminum subjected to variable amplitude loading. The predicted fatigue lives are compared with the experimental data and those predicted by Miner's rule, which show that the fatigue lives predicted by the proposed approach agree well with the experimental results and most of the errors are within a factor of 2. The proposed approach gives better prediction than the Miner's rule owing to the fact that it can take into account the loading history. Furthermore, the theoretical results tend to be non-conservative for the decreasing loading and the predicted results underestimate the experimental lives for the increasing loading.
