On one hand, a small Fracture Process Zone (FPZ) at the crack front is assumed in the existing mode II end-loaded split test methodologies based on Linear Elastic Fracture Mechanics (LEFM). However, mode II fracture has been reported to involve large FPZ and a fuzzy crack tip. Furthermore, the ELS test, is usually affected by geometrical non-linearities. This work proposes a closed-form solution based on the J-integral to determine the interlaminar fracture toughness in an ELS test. This solution avoids the need to measure the crack length, and is applicable when a large FPZ is present, as occurs in adhesive bonded joints between CFRP. In addition, because the ELS test involves large vertical deflections, a correction of the formulation for large displacements has been implemented. This new methodology has been compared to other methods available in the literature based on LEFM by means of an experimental campaign of delamination tests using unidirectional CFRP specimens in order to make a first validation of the method" , "dc.description.sponsorship": "The authors would like to acknowledge the support of the Spanish government though the Ministerio de Economía y Competitividad under contract TRA2015-71491-R" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Elsevier" , "dc.relation": "MINECO/PE 2016-2018/TRA2015-71491-R" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1016/j.compositesa.2016.08.020" , "dc.relation.ispartof": "© Composites Part A: Applied Science and Manufacturing, 2016, vol. 90, p. 670-677" , "dc.relation.ispartofseries": "Articles publicats (D-EMCI)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Assaigs de materials" , "dc.subject": "Materials -- Testing" , "dc.subject": "Materials compostos -- Deslaminatge" , "dc.subject": "Composite materials -- Delamination" , "dc.subject": "Mecànica de fractura" , "dc.subject": "Fracture mechanics" , "dc.title": "A data reduction method based on the J-integral to obtain the interlaminar fracture toughness in a mode II end-loaded split (ELS) test" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/embargoedAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.1016/j.compositesa.2016.08.020" , "dc.identifier.idgrec": "025697" , "dc.contributor.funder": "Ministerio de Economía y Competitividad (Espanya)" }
