3D numerical study of the transient behaviour on plasticity induced crack closure Camas-Peña, Daniel Antunes, Fernando Ventura López-Crespo, Pablo González-Herrera, Antonio Congresos y conferencias Daniel Camas, Fernando Antunes, Pablo Lopez-Crespo, Antonio Gonzalez-Herrera, 3D Numerical Study of the Transient Behaviour on Plasticity Induced Crack Closure, Abstract Booklet of the MSMF9, Edited by Pavel Sandera, Brno University of Technology, 2019, pp. 136. The numerical analysis of the plasticity induced crack closure requires the development of the plastic wake. Transient behaviour is observed when the crack starts to grow. The plastic wake length has an influence on the crack closure results and a great impact on the computational cost. Previous works have analysed the influence of this parameter considering bi-dimensional specimens in either plane strain or plane stress conditions. Lately, some three-dimensional models have appeared in order to analyse the crack closure phenomenon. The main scope of this study is to quantify and comprehend the minimum length required to stabilise the crack opening and closure values considering a three-dimensional model. On this purpose, a CT aluminium specimen has been modelled three-dimensionally and several calculations have been made in order to evaluate the influence of the simulated plastic wake. The numerical analysis is made in terms of crack closure and opening values. 2019-07-05T10:41:02Z 2019-07-05T10:41:02Z 2019 2019-07-05 conference output https://hdl.handle.net/10630/17956 eng 9th International Conference on Materials Structure & Micromechanics of Fracture Brno, Czech Republic 26 de Junio de 2019 open access
