A 3D Progressive Failure Model for predicting pseudo-ductility in hybrid unidirectional composite materials under fibre tensile loading Guerrero Garcia, José Manuel Mayugo Majó, Joan Andreu Costa i Balanzat, Josep Turon Travesa, Albert Materials compostos Esforç i tensió Mecànica de fractura Composite materials Strains and stresses Fracture mechanics This paper presents a three-dimensional Progressive Failure Model based on the chain of bundles able to represent the stiffness loss in unidirectional composite materials loaded in the fibre direction. A representative volume element with a random distribution of fibres with their own radius is considered. Complete stress distributions around fibre breaks are obtained by associating a damage variable to the loss of stress transfer capability along the ineffective length and applying local stress concentrations. The model has been validated by comparing it against the literature results and exhibits good agreement with hybrids and non-hybrid composites. The aim of this model is to simulate the tensile response of unidirectional composite systems dominated by fibre fragmentation mechanisms using a very reduced computational effort, even for larger representative volume elements, compared to micro-mechanical finite element models 2018-04 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion peer-reviewed http://hdl.handle.net/10256/26215 http://hdl.handle.net/10256/26215 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.compositesa.2018.02.005 info:eu-repo/semantics/altIdentifier/issn/1359-835X info:eu-repo/semantics/altIdentifier/eissn/1878-5840 Reconeixement-NoComercial-SenseObraDerivada 4.0 Internacional http://creativecommons.org/licenses/by-nc-nd/4.0 info:eu-repo/semantics/openAccess 13 p. application/pdf Elsevier © Composites.
