Texto completo da fonteThis study deals with one of the main research backgrounds developed by the Mineral Materials Laboratory: the formulation of highly durable concretes. Usually, chemical air-entraining agents are used to improve the durability to winter environment of concrete. This addition leads to a drastic strength decrease. Therefore, to prevent from this phenomenon, the research goal was to find physical admixtures leading to a good durability of matrices. This study is divided into three parts. In the first part, the literature about behaviour of concrete in presence of freezing and thawing cycles is reviewed. The different types of water present in the matrix are one of the most important parameters governing that behaviour. In the second part, different types of physical admixtures are investigated by means of cement pastes. The results obtained show that the lower is the crystallinity of the matrix and at interfaces the better is the behaviour of the paste. The flexural strength of specimens is more adequate than the compressive strength to describe the behaviour of the paste. From these data, a damage parameter (D) can be computed. In the third part, the influence of metakaolin addition is analysed. Mortars are cast, containing or not air -entraining agents. They present a smaller cement to sand ratio than standard mortars in order to reproduce the actual cement to aggregates ratio of concrete. A special apparatus is developed to subject the samples to coup led thermal and mechanical stresses. The study of microstructures before and after testing allows to exp lain the good durability of mortars containing metakaolin

Texto completo da fonteIn many engineering applications, assembled structures are widely used. These structures are composed of thin-walled members connected together by mechanical junctions, which characterisation is necessary to have a predictive model of the vibratory behaviour of assembled structure. Using the state vector formalism to describe the structural waves propagation in a bidimensional medium, a junction can be model intrinsically by a scattering matrix, which properties are studied in the bidimensional case. The case of a mono dimensional junction between two beams is developed: this junction couples extensional and bending waves. A measurement method of the coefficients of the scattering matrix is validated using a blocking mass junction. The study shows that slight modifications of the junction have a great influence on the scattering matrix coefficients

Texto completo da fonteThis study focuses on polyamide 66 matrices, formed as injection molded plates. The aim of the study is to highlight existing interrelations between microstructural organization and mechanic behavior.At first, the analysis is limited to one plate. A microstructural mapping has been done, and shows a typical injection molded organization, with evolutions in thickness and injection directions. Therefore, some areas can be differentiated, the superficial ones, those in contact with the mold, where the crystallization is induced by thermal gradient and shear stresses quite important, contrary to bulk areas which have known more stable conditions. Evolutions along the injection direction are more subtle and seem to be induced by the transportation of matter or different pressure conditions during the injection process.These microstructural differences are reflected on the mechanical plan and evolutions in the same directions have been observed. It appears that crystallites dimensions, perfection levels, constraint of amorphous phase or crystallinity ratio all impact on mechanical properties, even if interrelations are complex and not easy to discriminate.The influence of humidity on polyamide 66 material has been observed and discussed. This parameter controls the position of the material relatively to its glass transition and determines the way microstructure is implicated in deformation mechanisms.Finally, the study has been extended to different processing conditions. Although the evolutions that have been noticed were very small, they have helped to refine the analysis and confirm some points

Texto completo da fonteIn the field of Wave Chaos, statistics of ideal closed systems are nowadays well understood. However, much less is known for open systems, namely for systems those coupling to environment cannot be neglected anymore. Applying the Random Matrix Theory to the formalism of the effective Hamiltonian, spectral and spatial statistics of open chaotic systems are investigated analytically. Furthermore, theoretical predictions are checked systematically through numerical simulations of random matrices. In the spectral domain, the modifications induced by the openness on the spacings and the avoided crossings are illustrated using the resonance trapping effect. The well-known distributions of spacings and avoided crossings are generalized to open chaotic systems that allow to explain results based on microwave experiments. In the spatial domain, statistics of the non-orthogonal parameter, which measures the impact of the openness on the eigenfunctions of the effective Hamiltonian, are derived analytically and verified by numerical simulations modelling chaotic complexness parameter for a given resonance, is also obtained. This finding is confirmed through electrodynamics experiments

Texto completo da fonteString theory is the most promising candidate for the theory unifying all interactions including gravity. It has an extremely difficult dynamics. Therefore, it is useful to study some its simplifications. One of them is non-critical string theory which can be defined in low dimensions. A particular interesting case is 2D string theory. On the one hand, it has a very rich structure and, on the other hand, it is solvable. A complete solution of 2D string theory in the simplest linear dilaton background was obtained using its representation as Matrix Quantum Mechanics. This matrix model provides a very powerful technique and reveals the integrability hidden in the usual CFT formulation. This thesis extends the matrix model description of 2D string theory to non-trivial backgrounds. We show how perturbations changing the background are incorporated into Matrix Quantum Mechanics. The perturbations are integrable and governed by Toda Lattice hierarchy. This integrability is used to extract various information about the perturbed system: correlation functions, thermodynamical behaviour, structure of the target space. The results concerning these and some other issues, like non-perturbative effects in non-critical string theory, are presented in the thesis
