Full textFollowing a literature review focusing on the structure of bitumens and polymer modified bitumens, linear viscoelastic properties of paving grade binders were studied versus temperature and frequency. It is shown that neat asphalt cements can be looked upon as colloidal suspensions. As a consequence, the higher the dispersed phase content, the higher the modulus of the material. Moreover, modification of a bitumen by styrene-butadiene block copolymers induces a phase separation, the polymer rich phase being the dispersed phase for the investigated polymer contents (up to 6 % mass). The Palierne emulsion model describes the rheological properties of such multiphased materials

Full textThis dissertation tries to conjugate the comprehension and measurement work to decrypt mechanical properties of solids at micrometric and nanometric scales. The underlying questions are both to locate the limits of bulk properties (frontier of continuous medium mechanic) when the analysis window is narrowed and furthermore to describe new properties related to the decrease in measurement scale, if any. The non-linear mechanical analysis of Intermittent Contact Mode in AFM enables the monitoring of local mechanical properties of polymer such as storage and loss modulus or adherence. The surprising result of this analysis concerns the loss modulus whose measured value is greater than the macroscopic bulk one by one order of magnitude. The nanoindentation tests operated at a constant strain rate confirm and enrich this result : a 'characteristic heterogeneity length' has been introduced to define for this material the dimension under which the mechanical response differs from the one of homogeneous matter. This concept is canonical for heterogeneous materials at micrometer scale (i. E. Polymer blends) and is extended to material which are homogeneous in composition. Beyond this characteristic length, materials can only be described through statistical means. Another development of this study concerns the macroscopic description of materials using bulk constitutive equations. A particular effort has been held to describe viscoplastic behavior of glassy polymers (PMMA and PS). The viscoplastic data obtained by nanoindentation experiments and scratch tests may be interpreted with the help of Eyring molecular theory of activation energy. The results obtained at small strain rate (<0. 1 Hz) enables the computation of an activation volume of the polymeric material (lnm3 for PMMA et 0. 4nm3 for PS). These activation volumes are in good agreement with the theoretical ones and those obtained by macroscopic analytical methods. The scratch test experimental data are showing that at high strain rate (>0. 1Hz) the viscoelastic loss in contact increases and the calculated activation volume decreases. The phenomenon is interpreted as a transition to a B type relaxation of the polymeric material. The origin of the characteristic homogeneity length is still to be enlighten. Should this be understood as an evolution of the mechanical properties due to the narrowing of the analysis window? Is this length related to intrinsic properties of surface? In this case, surface mechanical properties would thus be heterogeneous

Full textMicrotubules—which define the shape of axons, cilia and flagella, and provide tracks for intracellular transport—can be highly bent by intracellular forces, and microtubule structure and stiffness are thought to be affected by physical constraints. Yet how microtubules tolerate the vast forces exerted on them remains unknown. Here, by using a microfluidic device, we show that microtubule stiffness decreases incrementally with each cycle of bending and release. Similar to other cases of material fatigue, the concentration of mechanical stresses on pre-existing defects in the microtubule lattice is responsible for the generation of more extensive damage, which further decreases microtubule stiffness. Strikingly, damaged microtubules were able to incorporate new tubulin dimers into their lattice and recover their initial stiffness. Our findings demonstrate that microtubules are ductile materials with self-healing properties, that their dynamics does not exclusively occur at their ends, and that their lattice plasticity enables the microtubules’ adaptation to mechanical stresses

Full textThe giant vesicles are a model of biological membranes often used in biophysical studies, for instance to investigate the mechanical properties of lipid bilayers. Improvements have been performed theoretically by use of a statistical analysis of the membrane fluctuations allowing to obtain a bending rigidity which is more precise, and regarding the electroformation method that allows now to form giant vesicles from different types of liposomes and proteoliposomes and furthermore under physiologically relevant conditions. A first characterization of the mechanical properties of GUVs under physiological buffer conditions has been presented with the magainin study. Magainin molecules induce a softening of the lipid bilayer by formation of local regions of high curvature on the membrane surface. The measurements of the bending rigidity can also be considered as an analytical tool enabling to detect membranes degradation, as illustrated by the study of the impact of different amphiphilic fluorophores. The study of sodium salts effects suggest a strong dependence of the mechanical properties of POPC bilayers on the solvent composition and demonstrates that the bending rigidity falls into the category of phenomena, which are perturbed by salt solutions according to the Hofmeister series. Finally the activity effects of the sodium-potassium pump on the membrane fluctuations have been studied. An enhancement of the membrane fluctuations is observed, as suggested by the major decrease of the bending rigidity. Besides, two distinct behaviors of the active membrane seem to be distinguished: a “pseudo-equilibrium” state and a “far-from-equilibrium” state

Full textThe miniaturization of electronic devices brings a strong demand for miniaturized power sources. Micro-batteries fit well with this demand. The micro-battery that we studied with the active multilayer system: Ti / a-Si / LiPON / TiOS (lithiated) / Ti has been fabricated by CEA-LITEN. My work is part of the STRESSBAT research project, supported by the French National Research Agency. This project is devoted to the improvement of the electrochemical and thermo-mechanical performances of this type of micro-battery. As the global thermo-mechanical properties of micro-batteries depend on the characteristics of their individual components, my thesis is dedicated primarily to the characterization of mechanical and thermal properties of each of them. We use two techniques both based on "pump-probe" method: picosecond ultrasonics and thermo-reflectance microscopy. Specifically, picosecond ultrasonics allows us to measure the velocities of longitudinal and Rayleigh waves, and if possible, the density of the studied material. These data will help us to deduce some elastic parameters like Young’s modulus and Poisson’s ratio. Thermo-reflectance microscopy allows us to extract the thermal conductivity and diffusivity with the help of the theoretical analysis of lateral heat diffusion. The Ti current collector, LiPON electrolyte, TiOS and a-Si electrodes are studied successively by these two techniques

Full textGlass is an ideal elastic-brittle material. Although cracking in glass has been much investigated, going back to the pioneer work of Griffith, investigations under confining pressure have not been done so far. Besides, as glass results of the solidification of variable fused silicate mix, the impact of thermal cracking in this material cannot be neglected. This is particularly significant when considering the study of the vitrified nuclear waste packages in geological storage condition where, in the worst case, fluid flow could be expected over a long time. Our study aims at investigating thermo-mechanical cracking effects on elastic wave velocities, mechanical strength and permeability under pressure to document damage evolution on SON68 glasses (original samples and thermally cracked - following a reproducible method - samples). The experimental setup enabled to monitor and vary independently confining pressure, axial stress and pore pressure at room temperature. An optimized set of sensors allowed us to perform measurements during the experiments of the local strain evolution and elastic wave velocities. We mainly observed that: (i) the original glass exhibits a linear and reversible mechanical behavior and isotropic elastic velocities, (ii) the thermal treatment has a strong influence on the glass mechanical résistance but (iii) a variable influence on the glass elastic properties Our results also exhibit the crack closure under confining pressure. As a consequence, the permeability decreased as a function of the cubic crack aperture up to interatomic diffusion level
