  • Resistance to crack growth due to cyclic fatigue loading is an important design consideration for elastomeric components subjected to compressive loading. Under this mode of loading the crack faces of fatigue cracks may be in contact due to the compressive loading and may or may not slide relative to each other depending on friction. The influence of friction effects on fatigue crack growth have been investigated in this paper. A fracture mechanics approach has been employed using finite element analysis techniques to study the influence of friction on the predicted fatigue crack growth in a specimen subjected to compression loads. The results predicted by the analysis have been validated by comparison with experimental data where the level of friction was varied by lubricating the crack surfaces. Good correlation has been found between the predicted crack growth and that measured from compression specimens with pre-existing cracks. The results show that the presence of friction can significantly reduce the rate of fatigue crack growth in. The results have significant implications for the evaluation of the fatigue failure of components subjected to compressive loading.
