Fabrication et caractérisations électriques et mécaniques d'un composite cuivre - carbone à architecture 3D

The aim of this thesis is to study the electrical and mechanical properties of copper-graphene composites. The scientific literature has shown, both experimentally and numerically, that it is possible to dop electrical properties with graphene,…

Polar textures in multiferroic BiFeO 3 -based superlattices

Recently, ferroelectric-based superlattices (SLs) have emerged and leaded to the discovery of exotic polar textures such as skyrmionic states or vortices in PbTiO 3 /SrTiO 3 SLs [1,2]. Thus, SLs offer a unique and promising new platform to study…

A numerical and experimental approach to blast protection with fluids, effect of impulse spreading

In the face of rapidly evolving challenges, new protection techniques against blast waves generated by high explosive detonations must be identified. The protection of vehicle floors is particularly relevant, especially against improvised explosive…

Non-local damage mechanics with evolving interactions for modeling quasi-brittle materials : anisotropic damage and gradient-enhanced Eikonal approach

Predicting the cracking nucleation and propagation is essential to describe structural response under complex loading conditions. Diffuse micro-cracks are observed to appear before coalescing into a macro-crack. In the case of quasi-brittle…

Mechanism-based modelling of the viscoelastic response of a unidirectional composite ply: validation of a new transversely isotropic model through analytical and numerical homogenisation

The viscoelastic response of long fibres, polymer matrix composites is mainly due to the deviatoric response of the matrix. This single microscale mechanism, however, results in different amount of viscous relaxation for the elastic constants…

Mechanical identification with the reconditioned equilibrium gap method: Formulation, analysis and comparisons

Full-field measurements are used to calibrate material parameters. The Equilibrium Gap Method (EGM), like other identification formulations that use full-field data, has the advantage of being direct for linear behavior and some nonlinearities,…

The liquid metal embrittlement of a reactive system at room temperature: α-brasses in contact with the liquid eutectic Ga-In

We studied the liquid metal embrittlement (LME) at room temperature of α-brasses by the liquid eutectic Ga-In (EGaIn). The EGaIn partially wets the α-brasses and forms the CuGa2 intermetallic. 3-point bending tests, Finite Element Analysis, and in…
