Abstract Scope |
The multiaxial fatigue behaviour of Ti6Al4V alloy fabricated by additive manufacturing is difficult to investigate experimentally. Machine learning (ML) can predict the dynamic mechanical behaviour, such as the multiaxial fatigue property, with less resources and more efficiency. This work uses three ML approaches: Support Vector Regression (SVR), Random Forest Regression (RFR) and Boosting Algorithms to predict the multiaxial fatigue life curve of Ti6Al4V alloy under different loading conditions. The test variables include stress ratio, laser powder bed fusion sample conditions, post-fabrication sample conditions, etc. The ML approaches are trained with experimental data from the literature. SVR handles nonlinear and complex data well, RFR processes small dataset efficiently, and Boosting Algorithms improve prediction accuracy by combining multiple models. These ML approaches capture the nonlinear characteristics of multiaxial fatigue behaviour of Ti6Al4V alloy and provide a reliable prediction of endurance limit. |
