title = "Correlation of the stress ratio effects on fatigue crack propagation threshold using a new parameter",
abstract = "In-situ SEM observations have revealed that fatigue crack propagation is caused by the shear band decohesion around the crack tip and the formation and cracking of the shear band is mainly caused by the plasticity generated in the loading part of a load cycle. This shear band decohesion process has been observed to occur in a continuous way over the time period during the load cycle. Based on this observation a theoretical analysis has been performed and a model has been set up to consider the effect of the applied stress ratio on fatigue crack propagation threshold. The obtained results have been compared with published test data and good agreement has been achieved. This method is very easy to use and no fatigue crack closure measurement is needed, therefore this model is significant in engineering application.",
