Abstract Scope |
The present study focuses on the fatigue life and fracture toughness behaviour of the additively manufactured Al 2024 alloy. The mechanical properties were investigated for different build orientations (horizontal (0°), and vertical (90°)). The test variables such as stress amplitude, build orientation, stress ratio, and post-processing condition (T6 ageing heat treatment) were considered for machine learning (ML) prediction. The experimental data were used to train the ML models such as Support Vector machine, Random Forest, Decision trees, and CNN and the trained models were used as predictive models for fatigue life estimation in Al 204 alloy. The pre-processed data set were used for training the ML models and the hyperparameters tuning were made using kernel function to ensure close match with experimental data. The predictive accuracy of these ML models was compared and discussed the hidden pattern of fatigue life influenced by process and dynamical loading conditions. |
