Micromechanical aspects of the inter-fibre failure in fibrous composite materials under bi-dimensional loads
(European Society for Composite Materials, 2004)
Many criteria have historically been proposed to predict failures in composites. Some of them were quasimimetically taken from metallic materials failure criteria and others were inspired by observation of the appearance ...

Failure initiation criterion in bonded joints with composites based on singularity parameters and practical procedure for design purposes
(Tailor & Francis, 2015)
Composite to metal adhesively bonded joints generates critical points where geometry and material properties change abruptly. These points (multimaterial corners) are potential locations for failure initiation. There exist ...

Evaluation of interfacial fracture toughness and friction coefficient in the single fiber fragmentation test
(Elsevier, 2011)
Single fiber fragmentation test is extensively employed to characterize the fiber-matrix interface in composites. A novel technique for evaluating fracture toughness and friction coefficient at the fiber-matrix interface ...

Non-conventional failures caused by the edge effect in cross-ply laminates made of ultra-thin plies
(Elsevier, 2023)
In a fatigue testing programme of carbon/epoxy cross-ply laminates made of ultra-thin plies, non-conventional failures are observed. These non-conventional failures consist in longitudinal cracks in the 90◦ layer parallel ...

Study of the effect of frequency on composite laminates under uniaxial fatigue loads
(AEMAC (Asociación Española de Materiales Compuestos), 2013-07)
Composites are nowadays widely used in primary structures. For safety reasons, the characterization of these materials under fatigue loads is being a very important task. The main advances in this field have been made ...

Fibre-matrix debonding in transverse cyclic loading of unidirectional composite plies
(2006)
Fatigue of composite materials is of great concern in load-carrying structures. In fact, most failures of composite structures can be attributed to fatigue. Due to the heterogeneity of composite materials at different ...
