Numerical modelling of three-dimensional fatigue crack closure: Plastic wake simulation. Camas-Peña, Daniel García-Manrique-Ocaña, José Manuel Pérez-García, Francisca González-Herrera, Antonio Método de elementos finitos Mecánica de fractura Materiales - Fatiga Versión aceptada. Poliítica de acceso abierto tomada de: .https://v2.sherpa.ac.uk/id/publication/12564 Finite element method has been broadly used to study fatigue crack closure. The simulated plastic wake length is one of the key modelling parameters involved. This paper presents a complete analysis in fatigue crack closure 3-D models. It is aimed at two aspects: the influence on the calculation of opening and closure values, and the effect on other main results. Conclusion indicates a 0.6· times Dugdale’s plastic size length to stabilise results as plastic zone or contact area, but a reduced length could be acceptable in terms of crack closure results. This suggests some independence among this parameter and fatigue crack closure. 2024-01-24T11:14:32Z 2024-01-24T11:14:32Z 2019-10-21 journal article Camas, D., Garcia-Manrique, J., Pérez-García, F., Gonzalez-Herrera, A., Numerical modelling of three-dimensional fatigue crack closure: Plastic wake simulation, International Journal of Fatigue, 131:105344 2020 https://hdl.handle.net/10630/29116 10.1016/j.ijfatigue.2019.105344 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Elsevier
