In-plane shear behaviour of non-crimp fabric laminates by means of 3D finite element analysis
(2013-09)
In order to characterize the in-plane shear behaviour of NCF laminates, experimental off-axis tensile tests of [+45,-45]2S laminates in different loading directions (parallel to the stitching yarns: warp-SP and normal ...

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 ...

PGD analysis of the heating of a composite laminate during ultrasonic compaction
(Asociación Española de Materiales Compuestos (AEMAC), 2013-07)
Compaction of composite layers just after placing them is a key requirement for the new out-of-autoclave in-situ curing techniques. A solution proposed for this task is the use of ultrasonic compactors. In fact, the ...

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 ...
