Abstract

Fatigue life evaluation of rotating components, such as shafts and discs, is an important aspect in ensuring the reliability and safety of mechanical systems. Using the stress-life (S-N) approach, this research presents a theoretical framework for predicting the fatigue life of such components. This research develops a purely mathematical model that is based on the fundamental principles of material mechanics and fatigue behaviour. This distinguishes it from conventional methods that often rely on experimental data or computational simulations.

The model incorporates the relationship described by S-N curves between cyclic stress amplitude, material properties and the number of cycles to failure. To improve the accuracy and relevance of the model, stress concentration factors, loading conditions, and material resistance limits are incorporated. The analytical tool can predict fatigue life under several operational conditions, such as bending and torsional stresses.
