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 ...

Study of the unfolding failure of curved composite laminates.
(2017-10-30)
The use of composite materials in structural applications has been considerably increased in the last years. This increment has introduced the use of composite laminates in complex components including highly curved zones. ...

Analysis of a Crack in a Thin Adhesive Layer between Orthotropic Materials: An Application to Composite Interlaminar Fracture Toughness Test
(Tech Science Press, 2010)
The problem of a crack in a thin adhesive layer is considered. The adherents may have orthotropic elastic behavior which allows composite laminates to be modeled. In the present work a linear elastic-brittle constitutive ...

Modelos analíticos y numéricos para la predicción del fallo por unfolding en vigas de material compuesto
(AEMAC (Asociación Española de Materiales Compuestos), 2013-07)
El fallo por unfolding en vigas de pared delgada fabricadas con materiales compuestos es un fallo que viene preconizado por componentes del estado tensional que no se consideran en los modelos de cálculo de barras y ...

A least squares procedure for the evaluation of multiple generalized stress intensity factors at 2D multimaterial corners by BEM
(Elsevier, 2012-03)
Detailed characterization of linear elastic stress states at corners and crack tips requires knowledge of the stress singularity orders, the characteristic angular functions and the generalized stress intensity factors ...
