AB Numerical models based on finite element method have been employed to analyse the plasticity inducedcrack closure phenomenon for a long time. These numerical analyses require the development of a plasticwake. During the development of the plastic wake a transient behaviour can be observed on the numericalresults. Most of these previous analyses have been performed considering bi-dimensional models. The useof three-dimensional models has been extended during last years. Nevertheless, the methodologyconsidered has been inherited from the bi-dimensional ones.Optimising the numerical parameters involved on the development of the plastic wake is a key issue to keepthe computational cost under control, particularly when a three-dimensional analysis is considered. Thisstudy presents a three-dimensional analysis of the influence of the crack growth scheme on fatigue crackclosure results. This three-dimensional analysis allows to study the influence of the number of loadingcycles not just on plane stress or plane strain conditions but all along the thickness.In the present work, a CT aluminium specimen has been modelled three-dimensionally and severalcalculations have been made in order to evaluate the influence of the number of loading cycles betweennode releases and after releasing the last set of nodes on fatigue crack closure results. The numericalaccuracy is analysed in terms of crack closure and opening values and in terms of strain and stress fields.
