Study of the influence of stacking sequence in the failure of crossply laminates manufactured with ultra-thin plies
(Asociación Española de Materiales Compuestos (AEMAC), 2024-01)
Numerous studies on the use of laminates manufactured with ultra-thin composite laminates have shown the existence of a significant delay in the appearance of damage, a phenomenon known as the Scale Effect. To study the ...

Experimental study of the use of ultra-thin plies in quasi-isotropic laminates under cyclic tension after impact
(Asociación Española de Materiales Compuestos (AEMAC), 2024-01)
In this work, the authors propose an experimental study on the possible improvement of the mechanical behaviour produced by ultra-thin plies in laminates subjected to cyclic loading after impact. More specifically, this ...

Caracterización numérica de esquinas multimateriales 3-D
(AEMAC (Asociación Española de Materiales Compuestos), 2005-06)
Se presenta un método eficiente para calcular los Factores de Intensidad de Tensiones Generalizados (FITG) asociados a términos de tensión singulares y no-singulares en aristas de esquinas 3-D formadas por la unión de ...

Evolution of the damage onset and morphology in [0/90n/0] laminates when increasing the ply thickness
(Elsevier, 2023)
In a previous paper, París et al [1], the authors proposed a physically based explanation (without employing fitting parameters) of the scale effect in composites, which gave a new insight on the in-situ strength concept. ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part I: Test proposal and numerical analysis
(Elsevier, 2012-07)
In the present work a general procedure for the experimental evaluation of Generalized-Fracture-Toughness values at multimaterial closed corners is defined. The lack of symmetries in the stress fields at multimaterial ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part II: Experimental results
(Elsevier, 2012-07)
In this paper the experimental part of the procedure for the Generalized-Fracture-Toughness determination in multimaterial closed corners with two stress singularities is presented. The so-called Generalized-Fracture-Toughness ...
