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 ...

Numerical and experimental analysis of ultra-thin plies in carbon/epoxy cross-ply laminates subjected to bending after tensile cyclic loading
(Elsevier, 2023-12)
As a result of a fatigue testing campaign in cross-ply laminates with different thicknesses in the 90° ply block (conventional and ultra-thin), different cracking patterns were observed. While laminates with conventional ...

Ballast shear effects on the dynamic response of railway bridges
(Elsevier, 2022-12-01)
Single-track railway bridges are susceptible of experiencing high levels of vertical acceleration on the deck that may be dangerously accentuated at resonance. This is especially critical for short-to-medium span simply ...

Motion-Based Design of Passive Damping Systems to Reduce Wind-Induced Vibrations of Stay Cables under Uncertainty Conditions
(MDPI, 2020-03)
Stay cables exhibit both great slenderness and low damping, which make them sensitive to resonant phenomena induced by the dynamic character of external actions. Furthermore, for these same reasons, their modal properties ...

Thermomechanical characterisation data of 30 g/m2 and 150 g/m2 cured unidirectional carbon/epoxy tape prepreg TP 402/T700S
(Elsevier, 2023)
With the aim to calculate through the Classical Laminate Theory the most reliable stress value generated in the 90° layer of cross-ply laminates tested under fatigue loading [1], the mechanical and thermal properties ...

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 ...

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 ...
