Premature failures in standard test specimens with composite materials induced by stress singularities in adhesive joints
(Elsevier, 2020-03)
This work presents three examples of standard test configurations, involving composite materials, where the presence of stress singularities induced by adhesive joints causes premature failures leading to underestimated ...

A note on Pageau et al. (1994) results for the order of stress singularities in multimaterial junctions
(Elsevier, 2020-05)
In 1994, Pageau, Joseph and Biggers Jr. evaluated “The order of stress singularities for bonded and disbonded three-material junctions”. Their work represented an important finding on multimaterial corners, since their ...

Riveted joints in composites, a practical tool to estimate stresses around the rivet hole
(Elsevier, 2021-05)
Riveted joints have different failure mechanisms, some associated to the failure of the rivet itself, and others associated to the materials to be joined. The failures associated to the material are mainly due to the stress ...

Comparison of the shear behavior in graphite-epoxy composites evaluated by means of biaxial test and off-axis tension test
(De Gruyter Open Ltd, 2021-01)
Characterization of shear behavior in composite materials remains a not fully solved problem. In the last fifty years, many different approaches have been proposed to solve this problem (rail shear, thin-walled tube torsion, ...

Experimental observations of fatigue damage in cross-ply laminates using carbon/epoxy ultra-thin plies
(Elsevier, 2023-02-15)
The damage mechanisms of cross-ply laminates under fatigue loading have been deeply studied during last years. In the case of quasi-static loads the so-called scale effect has recently acquired renewed importance after the ...

A review on failure theories and simulation models for adhesive joints
(Bellwether Publishing, Ltd., 2021)
In the framework of the Cost Action CERTBOND (Reliable roadmap for certification of bonded primary structures), a wide group of researchers from 27 European Countries have had the opportunity to work on the topic of ...

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 ...

University accreditations and publication of articles on education in Spain
(Routledge (Taylor & Francis), 2021)
In recent years, Spain has been far and away the leader in records of publications on education in indexed international journals. For several years, the accreditation requirements of university professorates have included ...

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 ...
