Der volle Inhalt der QuelleThe thesis has been realized within the framework of a partnership between the Cerema (Center for Studies and Expertise on Risks, Environment, Mobility, and Urban and Country Planning) and the ENTPE (National School for Public State Works). This work deals with the study and the simulation of the behavior of bituminous mixtures, in the domains of small and large amplitudes of solicitations. These domains correspond to the viscoelastic and viscoplastic behavior.First a bibliographical review on mechanical properties of the bituminous mixtures under small and large amplitudes of solicitations and a review of the several models describing the viscoelastic and viscoplastic behavior of bituminous mixtures is presented. This thesis is then composed of 5 main chapters.The two first deals with the development of the DBN model and mainly with the introduction of its new version EPPI (Elastic Perfectly Plastic and Isotropic). This formulation aims at describing the viscoelastic and viscoplastic behaviors together in a unique formalism, but simple enough to be implemented in a finite elements calculation program. This version of the DBN model is then implemented in a homogeneous computation code so as to be able to simulate classical experimental test.The two following chapter are devoted to the experimental campaign made during this research work. First a global description of the experimental procedures and test conditions is presented. Two kinds of tests are performed: complex modulus tests so as to characterize the viscoelastic behavior and simple traction tests for viscoplastic behavior. Finally results and observations issued from this campaign are detailed and some conclusions can be drawn.Finally the last chapter deals with the simulations performed thanks to the DBNEPPI model. These results aim at verifying the validity of the model introduced. Then a study about the transient effects during complex modulus tests on bituminous mixtures is detailed

Der volle Inhalt der QuelleNature is complex and must be approached in total modesty by engineers seeking to predict the behavior of underground openings. The engineering of industrial projects in underground situations, with high economic and social stakes (Alpine mountain crossings, nuclear waste repository), mean striving to gain better understanding of the behavioral mechanisms of the openings to be designed. This improvement necessarily involves better physical representativeness of macroscopic mechanisms and the provision of prediction tools suited to the expectations and needs of the engineers. The calculation tools developed in this work is in step with this concern for satisfying industrial needs and developing knowledges related to the rheology of geomaterials. These developments led to the proposing of a mechanical constitutive model, suited to lightly fissured rocks, comparable to continuous media, while integrating more particularly the effect of time.Thread of this study, the problematics ensued from the subject of the thesis is precisely about the rock mass delayed behavior in numerical modeling and its consequences on underground openings design.Based on physical concepts of reference, defined in several scales (macro/meso/micro), the developed constitutive model is translated in a mathematical formalism in order to be numerically implemented.Numerical applications presented as illustrations fall mainly within the framework of nuclear waste repository problems. They concern two very different configurations of underground openings: the AECL’s underground canadian laboratory, excavated in the Lac du Bonnet granite, and the GMR gallery of Bure’s laboratory (Meuse/Haute-Marne), dug in argillaceous rock.In this two cases, this constitutive model use highlights the gains to be obtained from allowing for delayed behavior regarding the accuracy of numerical tunnel behavior predictions in the short, medium and long terms

Der volle Inhalt der QuelleThis study is dedicated to the modeling of the size effect in the elasticviscoplastic behavior of nanocrystalline materials. Among others. This work aims at identifying the mechanisms responsible for the breakdown of the hall Petch law as well as to propose a new map of deformation which could aver usefull for future improvement of experimental fabrication processes. A detailed state of the art is presente in the first chapter of this theses where the structure of NC materials is presented as well the fabrication process and existing models. The state of the art is followed by a first attempt model where the effect of Coble Creep as well as that of Lischik sliding are quantified. The macroscopic behavior of the material is retrieved via the use of a self consistent micromechanical scheme. The second par tof this work i dedicated to the modeling of the recently introduced grain boundary dislocation emission mechanism. A new constitutive law , based on the formalism of thennally activated mechanisms, is introduced to describe the combined effect of dislocation emission and dislocation penetration. The study is completed by both a method of evaluation of the parameters based on molecular dynamics simulations and by finite element analyses
