Повний текст джерелаForming needs experimental set-up that make it possible to characterise materials behaviour at large strains, high temperatures and for strain rates between 10 et 500 s-1. This work is dedicated to the dynamic compression tests carried out on servo-hydraulic press. During these tests, oscillations appear on the load measurement: this is due to the vibration response of the set-up. A finite element model of the set-up is designed and the oscillations highlighted. A two steps treatment is then applied. First, the non-disturbed response of the material is obtained by inverse analysis of the set-up finite element model. This step enables to reduce the problem to the treatment of classical compression tests. Tested over a pseudo-experimental test, this method is then applied over the characterisation of industrial metals

Повний текст джерелаThis PhD concerned three different aspects, related both to simulation and resolution of structures from X-ray powder data:- The first aspect of my thesis aims at finding new solutions for solving complex structures for which a single method is unable to provide the solution when a single crystal is not available. Taking advantage of the expertise of the group in powder crystallography, solid state NMR and computer simulation, we decided to conjugate these three complementary approaches for trying to reach a solution. - The second part present the energetic studies of hypothetic porous germanates, which seem to be good candidates for the applications of porous solids (catalysis, gas storage or separation). - The third point concerned the extension of the AASBU to hybrid structures. The concept of SBU applies both to the inorganic and organic moieties. We had to find the proper ways for ‘sticking’ these bricks together in all the possible ways for providing not only the known structures, but also new virtual (or not yet discovered) ones. For two new structures, we decided to focus on the association of organic linkers with the rare inorganic trimeric units of three octahedra linked by a mu3-O, the chemical conditions of existence of which being established by the chemistry group of the laboratory. Coupled with either trimesic (MIL-100) or terephtalic (MIL-101) acids, this trimer gives two green powders. The indexation of the patterns lead to cubic symmetries (Fd-3m) and huge cell parameters (a = 72A for MIL-100 and 89A for MIL-101, corresponding to the unprecedented cell volumes of 380,000 and 706,000A3)

Повний текст джерелаSubmarine communications are the main usage of the very low frequency (VLF). This frequency band allows to radiate up to a few tens meter of depth and to a very long distance. Antennas for such telecommunications are necessarily small in regard to the wavelength. However, these structures are composed of hundred meters of thin metallic cables and their locations are often chosen for their dielectric characteristics or the structural advantage provided by the relief. To evaluate such antennas, we propose to use a home-made software, based on the TLM method. Such technique can be efficient for studying wide band electromagnetic problems in complex dielectric environment. Then we have improved the TLM Thin Wire model and we have evaluated its performances in realistic environment. In this document, we present our work and its validation by comparing our results to those obtained with the commercial software FEKO, based on the MoM, considered as the most suitable technique for this kind of problem. A solution assuring a good accuracy of the model for an arbitrary orientation of the Thine Wire in the 3D cartesian grid was proposed. We have also specified the limitations of the bent wire and the wires junction. In addition, we have studied the interaction between the wire and inhomogeneous media. This is an ambitious problem for which we brought some elements of answer but which remains a challenge. Finally, we have tested our software on some realistic antenna systems. The simulations of a valley span T antennas system allow to understand the functioning of such radiating structure and to show the interest of our method. The computation times are significantly lower with the TLM method than with FEKO to deal with antennas above such complex ground. However, the simulations of a Trideco antenna with aerial or buried radial ground plane showed the actual limitations of the TLM software which remains handicapped by an insufficient accuracy of the wires junction model and the inhomogeneous media interactions

Повний текст джерелаThis PhD thesis aims to develop experimental and numerical tools for the mechanical characterization and the numerical modeling of natural or artificial aortic valve tissues. These tools are intended to be used for the development of new biomimetic polymeric implants. Nowadays, almost 300 000 prosthetic valves are implanted every year worldwide. Two families of prosthetic valves are currently available~: mechanical and biological prostheses. However, both solutions suffer from major drawbacks. In this context, polymeric prostheses represent a promising alternative but currently suffer from insufficient material properties to be suitable for a long--lasting implantation. In this work, an experimental protocol using biaxial tensile tests together with full--field surface measurement and confocal microscopy is proposed. Since numerical simulation is intended to assist the design phase of new implants by predicting their mechanical behavior, a structure and a fluid solver are developed and coupled. Using experimental results, implemented constitutive models are calibrated through an inverse analysis procedure

Повний текст джерелаThis PhD work is part of the metrological development of optical methods applied to Fluid Mechanics to characterize 2D and 3D complex aerodynamic phenomenon. One of these techniques is digital holography which measures flow phase, directly linked to the refractive index integration. Gas density is deduced thanks to Gladstone-Dale relationship. If phase measurements are done along several viewpoints, gas density can be rebuilt in 3D by tomography. Firstly, digital holography was developed to measure high density gradients encountered in compressible wind tunnels. Then, three campaigns were made on steady 3D flows to compare performances of digital holography to differential interferometry and Background Oriented Schlieren (BOS) which measure light deviation, integration of the derivative of refractive index. 3D reconstruction algorithm developed by Onera/DMPE for 3DBOS, based on conjugated gradients method of a least squared regularized by Tikhonov minimization criterion, was adapted to phase measurements. Reconstructions with 36 different viewpoints were compared to reconstructions obtained by differential interferometry and BOS. Finally, the analysis of the viewpoint number needed to reconstruction showed its dependency with 3D complexity of the jet, what led to the implementation a digital holographic set-up with six simultaneous viewpoints to rebuild with success unsteady flows
