Estudio experimental a fatiga de laminados unidireccionales a 90⁰
(Grupo Español de Fractura, 2021-06-08)
La vida a fatiga de laminados unidireccionales a 90⁰ (UD-90) ha sido estudiada ante distintas condiciones de carga cíclica Tracción-Tracción (R=0.1). En primer lugar, el efecto de la porosidad se ha evaluado usando dos ...

Design of a cruciform specimen for biaxial transverse tests
(Asociación Española de Materiales Compuestos (AEMAC), 2013-07)
The objective of this paper is the design of the adequate geometry of the cruciform specimens to be tested under biaxial transverse loads. To this end Finite Element models have been developed. The analysis of the results ...

Behaviour of fibre/matrix interface cracks under biaxial stress state caused by edge effect in carbon/epoxy laminates
(Asociación Española de Materiales Compuestos (AEMAC), 2024-01)
A recent study about the ''edge effect'' phenomenon in cross-ply laminates made of ultrathin plies composites has shown the presence of a relevant stress component through the laminate thickness. This fact implies that ...

Manufacturing and testing of a cruciform coupon for biaxial transverse tests
(International Committee on Composite Materials, 2015)
The present study deals with the manufacturing of cruciform coupons to be tested under tensile biaxial transverse loads. The objective is to obtain a geometry that minimizes the effect of stress concentrations, maximizes ...

Experimental assessment of fatigue damage mechanisms in [04/90n]s laminates using carbon-epoxy ultrathin plies
(2021-06-25)
The damage mechanisms of cross-ply laminates under fatigue loading have been deeply studied during last years. In this work, the experimental assessment of two different cross-ply laminates under T-T loading (stress ratio ...

Device for biaxial testing in uniaxial machines. Design, manufacturing and experimental results using cruciform specimens of composite materials
(Asociación Española de Materiales Compuestos (AEMAC), 2013-07)
The present work deals with the design and manufacturing of a mechanical device to perform biaxial testing in universal (uniaxial) testing machines. A review of previous similar proposals is carried out and a new ...
