Interlaminar fracture testing of multidirectional laminates: on finitewidth effect and residual stresses Garulli, Torquato Arteiro, Albertino Blanco Villaverde, Norbert Renart Canalias, Jordi Plàstics reforçats amb fibra Fiber-reinforced plastics Mecànica de fractura Fracture mechanics Materials laminats -- Fractura Laminated materials -- Fracture Materials compostos -- Deslaminatge Composite materials -- Delamination Conferència presentada en la "21st European Conference on Composite Materials (ECCM21)", celebrada a Nantes, França, del 2 al 5 de juliol de 2024 i organitzada cada dos anys pels membres de la Societat Europea de Materials Composites (ESCM) Fibre reinforced polymers, and in particular laminated plates, are widely used in structural applications. Interlaminar fracture (delamination) is a critical damage mechanism for these materials. Interlaminar fracture toughness is characterised using unidirectional specimens. While the toughness at interfaces in multidirectional laminates may be different, there is no consensus on how to effectively characterise it, due to a number of challenges associated with the use of multidirectional specimens. In this work, we review in detail some of these problems, namely, 3-dimensional effects and residual thermal stresses. We then present a strategy to design a set of Fully-Uncoupled Multidirectional specimens enabling a further understanding of these problems European Union’s Horizon Europe research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 101061912 2024-07 info:eu-repo/semantics/bookPart info:eu-repo/semantics/publishedVersion info:eu-repo/semantics/altIdentifier/doi/10.60691/yj56-np80 info:eu-repo/semantics/altIdentifier/isbn/978-2-912985-01-9 info:eu-repo/grantAgreement/EC/HE/101061912/EU/ Enabling Interlaminar Fracture Testing of MULTIdirectional composite LAMinates for safe and efficient structures/ IFT-MultiLam Attribution-NonCommercial 4.0 International http://creativecommons.org/licenses/by-nc/4.0/ info:eu-repo/semantics/openAccess European Society of Composite Materials (ESCM) Ecole Centrale de Nantes BINETRUY, Ch. & JACQUEMIN, F.
