- The dominant mechanical failure for components is fatigue. Although unifying theories of fatigue have been proposed; material complexities, loading variations and experimental challenges have made it difficult to prove these theories. In particular, crack closure theory has split the research community based on differences found in results. The author of this paper has developed improved experimental results and numerical models to analyse the fatigue crack closure mechanism. In this current work the effects of variable loading are investigated using a long crack numerical model. Comparison of the numerical results with experimental data show good correlation with crack closure models.
