Full textThe aim of this work is to propose a general framework to obtain a gradient damage model from the micro-structural level. It is based, firstly, on the homogenization method to derive an effective medium from the microstructure, and secondly, on the variational formulation of a damage evolution law from the homogenized medium. We propose, as a first step, an approach based on asymptotic expansion and the variational method for homogenizing a periodic elastic medium. To model the localization of damage, this approach has been extended to a quasi-periodic heterogeneous medium. From an example of quasi periodically micro-cracked solid, we obtain an elastic energy that not only depends on the gradient of the damage but also the strain gradients. Based on the principle of energy minimization, we propose the construction of a gradient damage model from the elastic energy homogenized in the second part. By adding some hypothesis to simplify the model, we can construct localized damage and strain solutions in closed form. Finally, a numerical resolution scheme, which is based on an alternate minimization algorithm, is proposed for the one-dimensional traction bar test. From the numerical results, the advantages and disadvantages of the model are discussed

Full textThis thesis is constituted by two parts. In the first one, we study the equilibrium density fluctuation field of a one-dimensional reversible nongradient model. We prove, for the generalized exclusion process, the Boltzmann-Gibbs principle. This principle, first introduced by Brox and Rost, is the basic stage which enables us to show afterwards that our process converges in law to a generalized Ornstein-Uhlenbeck process, by applying Holley and Stroock's theory. In the second part, made in collaboration with C. Landim and M. Mourragui, we consider a nonlinear parabolic equation on a square with boundary conditions. Assuming that the diffusion coefficient is Lipschitz, we prove that the rescaled density field converges to the unique weak solution of the parabolic equation

Full textIn this thesis we study the equilibrium energy fluctuation field of a one-dimensional reversible non gradient model. We prove that the limit fluctuation process is governed by a generalized Ornstein-Uhlenbeck process. By adapting the non gradient method introduced by S. R. S Varadhan, we identify the correct diffusion term, which allows us to derive the Boltzmann-Gibbs principle. This is the key point to show that the energy fluctuation field converges in the sense of finite dimensional distributions to a generalized Ornstein-Uhlenbeck process. Moreover, using again the Boltzmann-Gibbs principle we also prove tightness for the energy fluctuation field in a specified Sobolev space, which together with the finite dimensional convergence implies the convergence in distribution to the generalized Ornstein-Uhlenbeck process mentioned above. The fact that the conserved quantity is not a linear functional of the coordinates of the system, introduces new difficulties of geometric nature in applying Varadhan's non gradient method

Full textThe use of multilayer is becoming increasingly important in the field of engineering, first in the industry, and more recently more and more in Civil Engineering. Whether complex blend of polymers, wood or concrete, significant efforts are required for accurate modeling of such materials. Indeed, phenomena induced anisotropy and heterogeneity are associated with these multi-material: edge effects, differential thermal expansion, delamination/detachment or nonlinearities viscosity type damage, plasticity in layers or interfaces. Among the models proposed in the literature, we found for example equivalent monolayer model or of "LayerWise" type (a kinematic per layer). Belonging to the second category, models have been developed in recent years in Navier allow a sufficiently detailed description to address specific issues mentioned above while maintaining a surgical nature. By introducing interface forces as generalized forces of the model, these approaches have demonstrated their effectiveness vis-à-vis the representation of details at inter- and intra-layers. It is then easy to offer behaviors and interfaces criteria and to be effective for modeling delamination or detachment, phenomenom very present in multilayered composites assembled and glued together. Therefore, a finite element program MPFEAP was developed in Navier laboratory. The model was also introduced as a User Element in ABAQUS, in its simplest form (perfect interfaces).A new layerwise model for multilayered plates is proposed in this dissertation, named Statically Compatible Layerwise Stresses with first-order membrane stress approximations per layer in thickness direction SCLS1. The model complies exactly with the 3D equilibrium equations and the free-edge boundary conditions. Also, a refined version of the new model is obtained by introducing several mathematical layers per physical layer. The new model has been implemented in a new version of the in-house finite element code MPFEAP.In parallel, a finite element program based on the Bending-Gradient theory which was developed in Navier laboratory, is proposed here. The model is a new plate theory for out-of-plane loaded thick plates where the static unknowns are those of the Love-Kirchhoff theory, to which six components are added representing the gradient of the bending moment. The Bending-Gradient theory is obtained from the Generalized-Reissner theory: the Generalized-Reissner theory involves fifteen kinematic degrees of freedom, eight of them being related only to out-of-plane Poisson’s distortion and thus, the main idea of the Bending-Gradient plate theory is to simplify the Generalized-Reissner theory by setting these eight d.o.f. to zero and to neglect the contribution of the normal stress σ33 in the plate model constitutive equation. A finite element program called BGFEAP has been developed for the implementation of the Bending-Gradient element. A User Element in Abaqus was also developed for the Bending-Gradient theory

Full textIn a first part, we deal with the so-called weakly continuous media according to an approach based on Riemann-Cartan geometry. We consider a solid body, modelled by a Riemannian manifold, and an Euclidean affine connection, which derives from the metric tensor. The mass density per volume unit may be assumed non constant and some defects, described by discontinuity fields of scalar fields or vectorial fields defined on the manifold, may appear in the body. The inevstigations do not concern the evolution of these fields but take into account their effects on the analysis of the deformation of the body. A possible generalization of this model is to consider an affine connection which deos not derive from the metric induced by the ambiant space. In a such case the torsion tensor and the curvature tensor associated with the affine connection are not necessary null, this corresponds to a second gradient continuum. Both tensors are used to describe the dislocation fields and disclination fields of Volterra. In a second part, we deal with the modelling of the Vickers indentation of glass. We consider a model which uses the schema of inclusion of Eshelby into a semi-infinite matrix, to analyse the stress and displacement fields during the loading process of the indenter. The objective is to determine the densification of the glass beneath the indenter. The semi-analytical results are positively compared with experimental data which are issue from LARMAUR

Full textA damage model in strain gradient from the homogenization method for brittle materials In this thesis, we have built a damage model to predict the fracture in brittle materials containing a source of stress concentration. We first developed a. Method of homogenization to establish the constitutive relations including the strain gradient for a heterogeneous material. When the strain gradient is riot negligible, the procedure of homogenization accounts for the strain gradient. In the constitutive law in a natural way. Then, as an application of this method. We constructed the constitutive relations in 2D for a linear elastic material with microcracks by adapting the self-consistent scheme. The obtained equations show that the behavior of the material depends not only on the density, but also on the average size of the mierocracks. This constitutive law has been extended to a damage model by adopting the concept proposed by Griffith. We implemented this strain gradient damage model into a finite element code. The numerical results were compared with the experimental data. It has been shown that the size effect observed in experimental studies was correctly reproduced by the proposed model. Moreover, the model is also well regularizated by the presence of strain gradient

Full textThis work focuses on the improvement of the antennas compactness used primarily for embedded systems while respecting the performance and competitiveness requirements. The approach explored consists in using artificial materials operating in transmission and designed by structuring the dielectric material on a scale smaller than the wavelength (sub-wavelength). This structuring makes it possible in practice to achieve a variation in the effective refractive index in order to produce diffractive elements capable of performing a microwave function. However, the particularity of this type of structured element is to mix several physical scales generating complexity in their study. The largest dimension of a structured component can reach several tens of wavelength, for example 20λ, while the minimum size of the sub-wavelength structures may be less than a fraction of the wavelength, as than λ / 20. This multi-scale aspect increases the simulation times of antenna devices integrating these structured elements, thus preventing any possibility of multi-parameter optimization in reasonable times. In order to exploit fully the potential of these structured materials, a numerical model of computation has been developed on the basis of optical paths. This model gives results on the maximum gain of structured diffractive lens antennas with an accuracy of 0.5 dB. The computation time of the model is of the order of the minute compared to more than 6 hours for a complete simulation with the electromagnetic calculation software CST Microwave Studio. The speed and precision of this model have been used to optimize the design of a structured diffractive lens. To illustrate the relevance of this structured approach, its performances were compared with those of Fresnel lens antenna and hyperbolic lens antenna. This comparison was carried out under identical footprint conditions with a length to diameter ratio L / D of 0.5. The gain of the structured lens was found to be 1.6 dB higher than the Fresnel lens and 2.7 dB higher than the hyperbolic lens

Full textThe long term behaviour of underground excavations is a social and economic stake, in particular in the context of storage in deep geological formation of high activity and long life nuclear waste. Several experimental galleries have been dug in the underground research laboratory (URL) of Meuse/Haute-Marne located close to Bure in France, where studies are leaded in order to understand the global behaviour of the constitutive rock which is the Callovo-Oxfordian (COx) argillite.The purpose of this PhD Thesis is to establish a modelling with Code_Aster of underground excavations, and especially of a Meuse/Haute-Marne laboratory gallery, taking into account non local approach, creep effect and hydromechanical coupling in the framework of the mechanics of porous media, and then to compare numerical results with available experimental data.The specific elastoviscoplastic model used in this study is the L&K model: it offers a coupling between instantaneous and delayed behaviour, and it takes into account the dilation, parameter which governs the volume strains of the material during a solicitation, and its strong variation, a specificity of geomaterials and so of COx argillite. The fluid flowing through the material adds a hydraulic component to the modelling, which is coupled to mechanic component thanks to Biot’s equations.Another novelty of this work concerns the coupling between such complex rheological behaviour and a non local approach in an industrial way. Among methods of regularization available in Code_Aster, the second gradient of dilation is well fitted to geomaterials. Its aim is to correct mesh dependency and numerical localized solutions.After describing numeric tools and setting parameters of the L&K model on laboratory tests, a good general agreement was found between numeric results and in situ measures, without resetting parameters. Time effects experimentally measured on displacement and pore pressure evolution are observed in the same modelling, validating the followed predictive approach
