The effect of frequency on tension-tension fatigue behavior of unidirectional and woven fabric graphite-epoxy composites
(Taylor & Francis, 2019-09)
In this paper, the effect of different values of load frequency on the evolution of the stress versus number of cycles to failure curve for a graphite-epoxy composite is studied. Two types of materials have been considered: ...

Predicting failure load of a non-crimp fabric composite by means of a 3D finite element model including progressive damage
(Elsevier, 2019-10)
A mesoscopic scale 3D finite element model of its representative unit cell is used to study the progressive damage of a [0,90]n non-crimp fabric laminate under compressive loading. The tows of the unit cell have been ...

Ageing effect on the low-velocity impact response of 3D printed continuous fibre reinforced composites
(Elsevier, 2023-12)
This paper aims to analyse the low-velocity impact performance of 3D printed continuous carbon fibre reinforced composites manufactured by fused deposition modelling. Moreover, the effect of ageing on the impact properties ...

Study of transversal and delamination cracks in [0/90] symmetric laminates by means of the linear elastic brittle interface formulation
(Grupo Español de Fractura, 2012)
En el presente trabajo se estudia el inicio y crecimiento de grietas transversales y de delaminación en laminados simétricos [0/90], bajo cargas de tracción en la dirección de las fibras en las láminas externas. El ...

Estudio del efecto escala en laminados [0,90n]s de material compuesto
(Sociedad Española de Integridad Estructural. Grupo Español de Fractura, 2021-07)
El efecto escala en materiales compuestos es conocido como el retraso en la aparición de daño en las láminas más débiles de un laminado (típicamente las láminas a 90 grados). Esta cuestión ha adquirido una enorme relevancia ...

Modelling the waviness of the fibres in non-crimp fabric composites using 3D finite element models with straight tows
(Elsevier, 2014-01)
A new approach to efficiently model the waviness of the fibres in non-crimp fabric (NCF) composites using mesoscale 3D finite element (FE) models with straight tows is presented. This approach omits the geometric curvature ...

Three dimensional finite element study of the behaviour and failure mechanism of non-crimp fabric composites under in-plane compression
(Elsevier, 2016-08)
The compressive behaviour and the mechanism responsible for failure of a [0,90]n non-crimp fabric (NCF) laminate are studied using a 3D finite element (FE) model of the representative unit cell at the mesoscopic scale. The ...

Inter-fibre failure under biaxial loads in glass–epoxy composite materials: Effect of the presence of a nearby fibre
(Elsevier, 2023-10)
Fibre-reinforced composite materials are especially prone to transverse failure. It appears at the lamina level following the mechanism known as matrix/inter-fibre failure. This mechanism of damage is associated with the ...

Fatigue life of unidirectional 90° carbon/epoxy laminates made of conventional and ultra-thin plies varying manufacturing and testing conditions
(John Wiley & Sons Ltd., 2023)
Unidirectional 90° laminates (UD-90) have been tested under tension–tension loading (R = 0.1) to comprehend the effect of different conditions on their fatigue life. Four different case studies have been evaluated: the ...
