Full textIn this study, we are interested in the modelisation of the dynamic behaviour of complex wave-guide networks. Two approaches are investigated. The first one is straight derived from the dynamic equations. This scheme is based on the concept of wave propagation in periodic structures and wave scattering on singularities. Properties of the propagation modes and scattering matrices are discussed for the general case of damped-undamped periodic elastoacoustic wave-guides. The concept of propagation modes is applied on another model dedicated to medium and high frequency ranges, uncorrelated wave assumptions and power balances lead to the general formalism of the Simplified Energy Method for vibroacoustic networks. This formulation, which takes into account all the propagation modes, does not consider the modal behaviour of wave-guides. New energy relations for guides and junctions are derived. In this context, the author focuses on the effects of dissipation on power balances. The energy levels obtained by this method are of great interest for the frequency and spatial analysis of energy exchanges between sub-systems. The performances of these energy models are systematically assessed for a large variety of vibroacoustic problems, both numerical and experimental

Full textThe development of new materials combining mechanical strength and lightness is a major issue in many industrial sectors. In order to use these materials, it is necessary to identify their mechanical properties. Inverse vibration methods can be used to determine these properties. These methods analyse the vibratory behaviour of the structure to identify the desired mechanical properties. Two methods are used in this thesis: the Force Analysis Technique and the Virtual Fields Method. They are applied here with the aim of identifying the bending stiffness and damping of a thin Love-Kirchhoff plate or an Euler-Bernoulli beam. First, the methods are applied using optical deflectometry, a full-field measurement method.By combining this measurement method with the two inverse methods, it is possible to obtain accurate maps of the bending stiffness and damping of the structure under study. Optical deflectometry measures the slopes of the displacement field. An inverse gradient operation is used to return to the displacement field. In order to eliminate this operation, the development of slope formalisms for the Force Analysis Technique and the Virtual Fields Method is proposed. These formalisms are tested with numerical simulations to identify the bending stiffness, followed by an experimental study. Secondly, a variant of the Virtual Field Method is developed. The aim of this variant is to apply the method when the number of measurement points per flexural wavelength becomes small. In fact, the Force Analysis Technique and the Virtual Field Method are no longer effective when the number of points per bending wavelength falls below 4. This is because a singularity at the bending wavenumber is present in the responses of the methods in wavenumber space. The Corrected Force Analysis Technique is a variant of the Force Analysis Technique which aims to remove this singularity using corrective factors. The application of these factors enables the method to be applied more effectively when the number of points per wavelength becomes small. A variant of the Virtual Fields Method has been developed for the same purpose. The method performs a local polynomial interpolation of the displacement field. The polynomial obtained is used to calculate analytically the integrals of the Principle of Virtual Work (a weak form of local equilibrium on which the Virtual Fields Method is based). These integrals are calculated locally on a virtual segment for the 1D case or on a virtual window for the 2D case. At each frequency, the length of the segment or window that allows the method to be applied when the number of points per wavelength is low is calculated. This length is referred to as the Frequency Adapted Length. The variant is therefore called the Frequency-Adapted Virtual Field Method. It is developed for the Euler-Bernoulli beam and the Love-Kirchhoff plate and is tested on experimental data to identify the complex bending stiffness of a locally damped plate

Full textThe control of the electrical properties of MIS systems is an important step for the development of MISFET devices. The aim of the present work is to improve the electrical characterisation techniques for MIS structures. In the first section of this thesis, the electrical performance of MIS capacitors made on n-type InP substrates, with boron nitride as an insulator (Au/BN/InP), has been studied. RF and microwave plasma-enhanced CVD (PECVD) techniques are used for the deposition of the dielectric. It is shown that some observed anomalies (essentially : the impurity redistribution in the substrate and mobile charges in the insulator) often affect interface states distributions evaluated by conventional capacitance methods. To avoid these limitations, we have developed a new method, based on modified BTS (bias temperature stress) measurements, to determine the density of interface traps D(it). The interface states distributions obtained by this technique have been compared to those obtained from capacitance-voltage (terman analysis) and DLTS measurements. We have then examined the influence to interface states in doping profile determination. An adaptation of the capacitance method, allowing the elimination of the profile distortion due to this influence, has been proposed. Furthermore it has been shown our method we can determine the signs and concentrations of mobile and fixed charges in the insulator. The observed frequency dispersion phenomena have been discussed. In the second section, we propose a new method to determine the surface doping concentration N(s), and flat-band voltage Vfb, for implanted MOS (SiO2/Si) structures. A technique to extract the insulator capacitance Ci, from C-V characteristics near flat band conditions, is also proposed. This research is motived by the trend to scale MOSFET's to deep submicron channel length, which increases the accuracy needed in modelling and measurement of these devices. Our methods are illustrated and validated by application on simulated MOS structures, using the 2D devices simulator ATLAS II (PISCES version of SILVACO)

Full textThe trend in the microelectronics industry is towards miniaturisation, from transistors to the integrated circuit package. This constant desire of compactness is certainly motivated by economic reasons, but also by the perspectives to gain in performance, power and ergonomics. In early 90s, 0.8 µm was the transistors gate length at major semiconductor manufacturers. The length has been reduced to 6 nm with a density of integration of 125 million transistors per square millimetre. However, such a transition does not come without consequences, as far as it concerns fracture mechanisms, it is particularly true regarding the low-k dielectrics. This family of materials, although porous and fragile, is essential to ensure the insulation in the circuitry of an increasingly dense Back-End of Line (BEoL), with increasingly fine lithography. Besides, due to its porosity, it also has a hydrophilic behaviour which greatly reduces both its insulation quality and stress strength. For all these reasons, the seal ring, the copper interconnection structure that encircles the chip, was implemented to (i) ensure the mechanical integrity of its interior, containing the electrically active part of the die, and (ii) to protect it from moisture and other chemicals intrusions. Hence the interest of this work to address the thermomechanical stresses and cracking phenomena which are articulated around the BEoL. To do so, various paths revolving around the same line of research, mechanical integrity in microelectronics systems, are proposed. (i) Two ways of evaluating stress fields in active silicon and passive BEoL are investigated: by implementing sensor structures based on the principles of piezoresistance and extensometry respectively. (ii) The Four-Point Bending technique is benchmarked, and readapted to account for the crack length, for cracks advancing is homogeneous (decohesion) and heterogeneous (debonding) thin films structures. (iii) A Finite Elements approach, combined with Cohesive Zone Models under Small-Scale Yielding conditions, is proposed to analyse the influence of the arrangement and plasticity of copper in the interconnections in the resistance to crack advance

Full textThe development of cement, partially substituted by calcined clays, is taking place against a backdrop of strong international demand for low-carbon cements. The aim is to reduce the cement industry's overall CO2 emissions. Calcined clays represent a serious alternative due to their high pozzolanic reactivity and wide availability. Various parameters influencing the behaviour of calcined clay have been studied, such as calcination conditions, the nature of the calcined clays and the impact of their structure on their reactivity. Although the use of calcined clays in this context is generally associated with a high demand for water, the parameters influencing this demand are poorly understood.The present work explores the high water demand of cement-calcined clay mixtures in the first moments of dry material contact with water (< 20 min). The development of an experimental methodology has made it possible to explore the water demand of calcined clays and cement-calcined clay mixtures on different scales. This approach ranges from the ‘instantaneous’ characterisation of the state of the material using various experimental methods, to the continuous study of the material and mixtures studied using microcalorimetry. The development of this work has led to an initial descriptive approach to the overall water demand of a mixture, with the qualification and quantification, if possible, of each contribution. The water demand at the particle level, with the wetting water, and the water demand at the mixture level, with the water present in the inter- and intra-agglomerate spaces, the water present in the inter-particle spaces (deflocculated system) and the water participating in the formation of hydrates, are thus described

Full textLast three wars have left millions of tons of unexploded ordnance (UXO) in French subsoil. They put the population and the environment at risk. Geophysics and particularly the magnetic methods present some solutions to characterise and locate those generally magnetised objects. The multi-sensor magnetic cartography device designed at EOST has some faults. Consequently, (i) the production of a new digitizer, (ii) the acquisition of a new geo-spatial positioning system and (iii) the use of an extra sensor to correct the time-related variations of the magnetic field allow us to improve our cartography quality. Likewise, multi-altitude measurement allow us to optimise the time in relation to the wanted cartography definition. According to the approximation generally used in magnetism theory, the anomaly is insignificant compared to the regional magnetic field. At the same time as my previously described field work, a thorough study of the dipole theory, allowed me to evaluate that this approximation results in a non-negligible mistake reaching 16% of the anomaly. The inversion results are sensible to this mistake. Moreover, l've developed an algorithm based on Euler deconvolution and l've re-evaluated the method already used which is based on analytic signal. After I compared some of the inversion methods, the one based on the analytic signal seems to ascertain the better the object characteristics
