Characterization of 3D printed long fibre reinforced composites
(Elsevier, 2018-02)
Additive Layer Manufacturing (ALM) process is used in the present investigation to manufacture long fibre reinforced composite parts using the MarkOne® 3D-printer. In ALM, a continuous filament (including a tow of fibres) ...

Accurate determination of the stiffness properties for an elastic interface under peeling conditions between homogeneous materials
(Elsevier, 2022-04)
In this paper, several models for analysing peeling tests are considered, including numerical models based on FEM, semi-analytical approaches, and beam models including an elastic interface. Results show that none of the ...

On the 3D extension of failure models for adhesive joints under mixed-mode fracture conditions: LEBIM and CZM
(Elsevier, 2019-04)
Interface models for triggering damage events have been extensively used in many engineering applications due to their inherent versatility and relatively simple numerical implementations. Usually, the non-linear behavior ...

Tensile and shear strength of bimaterial interfaces within composite materials
(Elsevier, 2016-03)
The determination of the tensile and shear strengths of homogeneous materials can be easily performed by standard tensile and shear (e.g. Iosipescu) tests. Nevertheless, when the determination of these strengths involves ...

A new in situ peeling test for the characterisation of composite bonded joints
(Elsevier, 2018-10)
At the moment, bonded joints quality on composites used in aeronautical industry is verified based on the determination of the interlaminar fracture toughness (Gc) obtained by means of the Double Cantilever Beam (DCB) or ...

A powerful matrix formalism for stress singularities in anisotropic multi-material corners. Homogeneous (orthogonal) boundary and interface conditions
(Elsevier, 2022-06)
A computational code based on a semianalytic procedure for the determination of the characteristic exponents and the singular stress and displacement fields in multi-material corners is developed. Linear elastic anisotropic ...

Influence of the size and depth of a circumferential notch on the impact behavior of streetlights. A passive-safety concept
(Elsevier, 2015-07)
Impact tests on weakened streetlights were carried out using a high energy pendulum. The weakening mechanism consists of a circumferential notch at the base of the streetlight. The objective is twofold: firstly to reduce ...

A least squares procedure for the evaluation of multiple generalized stress intensity factors at 2D multimaterial corners by BEM
(Elsevier, 2012-03)
Detailed characterization of linear elastic stress states at corners and crack tips requires knowledge of the stress singularity orders, the characteristic angular functions and the generalized stress intensity factors ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part I: Test proposal and numerical analysis
(Elsevier, 2012-07)
In the present work a general procedure for the experimental evaluation of Generalized-Fracture-Toughness values at multimaterial closed corners is defined. The lack of symmetries in the stress fields at multimaterial ...

Determination of Generalized Fracture Toughness in composite multimaterial closed corners with two singular terms - Part II: Experimental results
(Elsevier, 2012-07)
In this paper the experimental part of the procedure for the Generalized-Fracture-Toughness determination in multimaterial closed corners with two stress singularities is presented. The so-called Generalized-Fracture-Toughness ...
