Повний текст джерелаCe mémoire de maîtrise présente une étude préliminaire pour comprendre comment réaliser l'analyse modale d'une turbine hydraulique de type Francis. Au cours du projet Tr-Francis, il est prévue de réaliser des mesures de déformations et de réaliser une analyse modale à l'aide de jauges de déformation collées sur la turbine lors de son fonctionnement. Pour ce faire, il est nécessaire de comprendre comment installer les jauges de dé- formation sur la turbine. Tout d'abord, des expérimentations ont été réalisées afin de comprendre les raisons pour lesquelles les jauges de déformation ne fonctionnent pas sous l'eau. Différentes technologies de jauges de déformation et différents produits de protections ont également été testés. Il est également nécessaire de comprendre comment réaliser une analyse modale à partir de mesures de jauges de déformation. Sumali à développée une nouvelle méthode d'analyse modale par mesure de déformation sur une poutre. A travers ce mémoire, cette méthode est étendue pour réaliser l'analyse modale d'un anneau. La méthode est tout d'abord prouvée mathématiquement puis à l'aide d'une simulation numérique. Finalement, en excitant un anneau instrumenté de jauges de déformations avec un marteau d'impact puis avec un piézo-actionneur, la fonctionnalité de la méthode est prouvée.
This Master's thesis presents a preliminary study to understand how to perform the modal analysis of a Francis hydraulic turbine. During the Tr-Francis project, it is planned to carry out deformation measurements and perform a modal analysis using strain gauges bonded to the turbine during its operation. It is then necessary to understand how to install the strain gauges on the runner. Experiments were conducted to understand why the strain gauges have a limited lifetime underwater. Different strain gauge technologies and different protection products have also been tested. It is also necessary to understand how to perform a modal analysis from strain gauge measurements. Sumali has developed a method to perform modal analysis using deformation measurement on a beam. Through this thesis, this method is extended to perform the modal analysis of a ring. The method is first developped and then validated using numerical simulations. The method is first proven mathematically and then using a numerical simulation. Finally, by exciting an instrumented ring of strain gauges with an impact hammer and then with a piezo-actuator, the functionality of the method is proven.

Повний текст джерелаTo preserve the integrity of vehicle passengers during a crash constitutes a major goal for the automotive manufacturers since many years. The aim of this Ph-D thesis is to analyze the effect of a plastic prestrain on crash properties of a crash-box structure. The loading history is composed of at least two phases. The first phase is the forming process, in general under quasi-static conditions. The subsequent loading is due to a crash event. The behavior of three steels frequently used in the automotive industry has been studied (BH260, DP600, TRIP800). The experimental characterization of the steels shows the effect of a quasi-static prestrain on subsequent dynamic tensile curves. In addition, a large experimental crushing campaign of structures revealed that the prestrain process improves the crash behavior despite a reduction of the wall thickness. Two phenomenological models are then proposed to describe the strain-hardening effects and strain-rate sensitivity of metals. The model predictions show a very good agreement with experimental results for a wide range of strain-rate. Strain-rate history effects are well accounted for by one of the models. Finally, a numerical approach is performed where the variables calculated during the stamping (residual stress, equivalent plastic deformation, final thickness) are taken into account during the crash simulation under dynamic loading

Повний текст джерелаThe Portevin Le Chatelier (plc) effect is one of the most fascinating forms of the plastic flow instabilities. This phenomenon consists in the repeated generation and propagation along a tensile specimen of sharply edged bands of localised plastic deformation. Experiments show that the plc effect is usually unperiodic and some models suggest that the instability might lead to determinist chaotic behaviour. In this work, this suggestion is investigated using a method of analysis based on the qualitative information contained in the temporal variations of the stress in loading with constant applied cross-head velocity. In this thecnic of a analysis, various implements are used : at first the method of delays is used to reconstruct phase trajectory of the dynamical system. The method use time series constututed from temporel variations of one state parameter of the system. The fractal structure of the reconstruction obtained suggest that the trajectory lie on a strange attractor which is the reflection of determinist chaotic dynamic. Indeed, confirmation of the existence of a strange attractor is done by calculating dimension of this attractor using the Grasseberger-Procaccia algorithm. The dimension obtained is lightly upper than three. Finally, sensitivity to initial conditions is prouved using the Gao-Zheng algorithm which give a positive value of the Lyapunov exponent. The above results permit to conclude that the underlying dynamic of the plc effect is determinist. Indeed, the dimension value of strange attractor suggests that a phenomenon description must take into account at least four state parameters of the system. This is compatible with some theories

Повний текст джерелаSoil deformation phenomena of natural (tectonic) or anthropic origins (over exploitation of groundwater, embankment) can have adverse effects on the environment and on human life. A good understanding of the mechanism of deformation is essential to mitigate or eliminate risks to infrastructure and natural environments. In this study, it is proposed to apply the interferometric method to study the mobility of an urban and suburban area of Tunis City, which is the main socio-economic center of Tunisia.Seismotectonic analyzes were carried out in the study area to better understand the seismic and structural context of the North East part of Tunisia while being based on the different interpretations made from focal mechanisms and mapping epicentres in this area. This analysis made it possible to deduce the existence of an NW-SE compressive regime that fits well with the existing regime at the regional level. This mapping also allowed the detection of the different zones marked by a relatively large seismic activity with a moderate magnitude and which coincide well with the major accidents that are at the level of the study area. Subsequently, a geomorphological analysis approach of the study area was carried out, which made it possible to highlight the different existing tectonic structures and to distinguish the different morphological units. It has been shown that geomorphological analysis has limitation to interpret the morphodynamic context of the study area and therefore the interferometric technique has proven to be an effective methodology for detecting and monitoring soil displacements with millimeter precision and also improving our understanding of current deformations. Indeed, the application of differential SAR interferometry made it possible to nether identify areas with natural subsidence risks or analyze the deformations of the topographic surface associated with anthropic phenomena. To better assimilate the morphodynamic context of the study area, the interferometric method of Small Baseline Subset (SBAS) developed by Berardino et al. (2002) has been chosen. The analysis of Envisat ASAR (2003-2007, descending satellite orbit) and Sentinel-1B (2016-2018, ascending satellite orbit) SAR data allowed us to obtain soil deformation maps associated with time series of velocity of the study area. These analyzes showed the existence of a differential settlement phenomenon in the region of Tunis and the Mornag plain by quantifying it quite accurately. Therefore, by combining SBAS results with geological, hydrogeological and geotechnical information, we have been able to explore some of the links between soil subsidence and its main control factors, in particular:- a differential settlement detected around the Lake of Tunis region, which is probably due to the nature of highly compressible alluvial sediments with bedrock depths sometimes exceeding 65m;- a subsidence of the Mornag plain, whose overexploitation of groundwater and the compressibility of alluvium were the driving forces of these deformations
