AB Since long time, fatigue crack closure has been studied by means of finite elementmodels. Initially by bi-dimensional models and recently, due to the higher computationalcapabilities, the use of three-dimensional models has been extended, providing a widercomprehension of the problem. Starting with the methodology used for 2D cases, a specificmethodology for 3D models has been developed. Key parameters affecting the model have beenanalyzed and recommendations have been established. The numerical accuracy is evaluated interms of crack closure and opening values. They main issues studied are the material behaviour, theloading cycles and crack growth scheme, the contact simulation, the meshing and the element sizeat the crack tip and along the thickness, the plastic wake computed and the opening and closuredefinition considered. This paper summarises the main learning and recommendations from thelatest numerical modelling experience of the authors.
