Numerical analysis of the crack paths produced by fibre–matrix interface failure in cross-ply LFRP laminates
(Elsevier, 2022-03)
The so-called matrix failure, also named inter-fibre failure, is one of the main failure mechanisms in long fibre reinforced polymers (LFRPs). This mechanism is characterized by the debonding of some fibres when transverse ...

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 ...

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, ...

Modeling fracture of multidirectional thin-ply laminates using an anisotropic phase field formulation at the macro-scale
(Elsevier, 2023-06)
An equivalent single layer approach to model fracture events of multidirectional balanced thin-ply laminates via the use of the Phase Field method is explored. The inherent anisotropic nature of a multidirectional laminate ...

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 ...

On different 3D printing methods and fracture performance in DCB composite specimens including structured interfaces
(Elsevier, 2022-12)
This work experimentally analyzes the influence of the printing direction on the fracture resistance capabilities of composite specimens incorporating structured interfaces in their geometrical definition. In particular, ...

Multi-impact response of semicylindrical composite laminated shells with different thicknesses
(Elsevier, 2023-04)
Nowadays, composite materials are increasingly used in the most diverse areas of engineering, where non-planar geometries begin to be quite frequent. However, the existing knowledge about its mechanical performance is still ...

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 ...
