Résumé :
Forsterite (Mg2SiO4) is one of the major planetary materials, and its behavior under extreme conditions is important to understand the interior structure of large planets, such as super-Earths, and large-scale planetary impact events. Previous shock compression measurements of forsterite indicate that it may melt below 200 GPa, but these measurements did not go beyond 200 GPa. We report the shock response of forsterite above ~250 GPa, obtained using the laser shock wave technique. We simultaneously measured the Hugoniot and temperature of shocked forsterite and interpreted the results to suggest the following: (i) incongruent crystallization of MgO at 271 to 285 GPa, (ii) phase transition of MgO at 285 to 344 GPa, and (iii) remelting above ~470 to 500 GPa. These exothermic and endothermic reactions are seen to occur under extreme conditions of pressure and temperature. They indicate complex structural and chemical changes in the system MgO-SiO2 at extreme pressures and temperatures and will affect the way we understand the interior processes of large rocky planets as well as material transformation by impacts in the formation of planetary systems.

Résumé :
The C6H6:C6F6 cocrystal is one of the simplest organic cocrystals with a molecule having a C–F bond and without any hydrogen bonding. It has a crystal structure very different from its constituents, C6H6 and C6F6, and its higher melting point indicates its increased stability relative to these two materials. So far, no studies are available on the phase transitions of this interesting adduct under dynamic compression. In this study, we present the findings of phase transitions of an equimolar mixture of C6H6:C6F6 observed under rapid shock compression at pressures of up to 4.15 GPa using time-resolved Raman spectroscopy. The compression is driven by a 2 J Nd:YAG laser with an 8 ns pulse length. Four prominent modes at 370 cm−1 (ν10F mode), 443 cm−1 (ν6F mode), 560 cm−1 (ν1F mode), and 991 cm−1 (ν1H mode) exhibit a blue shift with scaling factors of 2.41, 2.26, 2.39, and 2.67 cm−1/GPa, respectively. The liquid → solid-I phase transition is observed at around 0.49 GPa shock pressure. The second phase transition from solid-I → solid-VI is observed between 1.32 and 2.60 GPa, and no signature of the solid-V phase is observed unlike in the case of static compression[Wang et al., J. Phys. Chem. C 120, 29510 (2016)]. Another phase transition solid-VI → solid-VII is observed between 3.9 and 4.15 GPa. The shock velocities in the sample at two laser intensities, 1.47 GW/cm2 (300 mJ) and 2.46 GW/cm2 (500 mJ), are calculated by measuring the intensity ratio of Raman modes emerging from the shocked region to that of the whole sample and are 3.13 and 4.05 km/s, respectively. To compare with the experimental results, 1D radiation hydrodynamics simulations are also performed. The experimental and simulated shock velocities are in good agreement. The mode Grüneisen parameter for the ν1H, ν1F, ν6F, ν10F, and ν10' F modes are γi = 0.011(2), 0.022(2), 0.011(1), 0.024(3), and 0.379(14), respectively.

Résumé :
The structural phase transformation and crystallization of amorphous silica at 500 K under high pressure are investigated by molecular dynamics simulation. Under compression, there is a structural transformation from tetrahedral- to octahedral-network via SiO5 units. Structural transformation occurs strongly in the 5–15 GPa pressure range and there exist three structural phases corresponding to SiO4, SiO5, and SiO6. Beyond 15 GPa, octahedral-network is dominant. At pressure higher than 20 GPa, octahedral network tends to transform to crystalline phase (stishovite). Mechanism of structural transformation is clarified via coordination-number, bond-angle distributions, bond length distribution, and 3D visualization. The size-distribution of phase regions is also determined in this work.

Résumé :
Electrical resistance measurements of aluminum foil are conducted under shock compression using the electric contact technique. Shock wave pressure p dependences of the electrical resistance R and the resistivity r are obtained for pressure range up to 22 GPa. The found dependence R(p) is a monotonically increasing smooth function of the pressure. The dependence r(p) is more complex: with increasing pressure, the electrical resistivity first decreases and then increases.

Résumé :
La constante augmentation du nombre de petits débris spatiaux (≈1 mm) motive l’étude du comportement sous choc de matériaux innovants pour renforcer les blindages des structures spatiales actuellement utilisées. De précédentes études ont mis en lumière le potentiel des verres métalliques base zirconium comme matériaux de blindage lors d’expérience d’impacts hypervéloces sur une configuration de type Whipple. Dans ces travaux sur le comportement dynamique de verres métalliques du système ZrCuAl, nous avons fait le choix d’utiliser des lasers de puissance comme générateur de chocs plutôt que des lanceurs notamment pour atteindre des vitesses de déformation plus élevées (> 2×10⁷ s⁻¹) et, surtout, plus représentatives de celles générées lors d’impacts de débris spatiaux hypervéloces. Des campagnes expérimentales sur les installations du Laboratoire pour l’Utilisation des Lasers Intenses et du CEA ont permis : de compléter les courbes d’Hugoniot de verres métalliques massiques et sous forme de rubans ; de mettre en évidence une évolution de la limite à rupture avec la vitesse de déformation atteignant 13,6 GPa, soit presque 7 fois la valeur en quasi-statique ; d’observer de la cristallisation sous choc de la composition Zr₅₀ Cu₄₀ Al₁₀ avec des mesures de DRX sous choc ; et enfin de construire une équation d’état basée sur le modèle de Mie-Grüneisent référencée à l’isotherme de Birch
The constant augmentation of small sizes space debris (≈1 mm) incites the study of innovative materials behaviour under shock compression to reinforce the actual space structure shields. Previous studies have highlighted the potential of Zirconium-based metallic glasses as shielding components with hypervelocity impact experiments on a Whipple shield configuration. In this work on the dynamic behaviour of metallic glasses from the ZrCuAl system, we have chosen to use high-power lasers as shock generator rather than launchers, in particular to achieve higher strain rates (> 2×10⁷ s⁻¹) and, above all, more representative of those generated during hypervelocity impacts of space debris. Experimental campaigns on Laboratoire pour l’Utilisation des Lasers Intenses and CEA facilities have made it possible to: complete the Hugoniot curves for bulk metallic glasses and ribbons metallic glasses; to highlight an evolution of the spall strength with the strain rate reaching 13.6 GPa, i.e. almost 7 times the quasi-static value; to observe crystallisation of Zr₅₀ Cu₄₀ Al₁₀ composition with XRD measurements under shock compression; and finally to build an equation of state based on Mie-Grüneisen’s model considering the Birch’s isotherm formulation as a reference

Texte intégral
Résumé :
The response of porcine adipose and skeletal muscle tissues to shock compression has been investigated using the plate-impact technique in conjunction with manganin foil pressure gauge diagnostics. This approach has allowed for measurement of the levels of uniaxial stress imparted to both skeletal muscle and rendered adipose tissue by the shock. In addition, the lateral stress component generated within adipose tissue during shock loading has also been investigated. The techniques employed in this study have allowed for equation-of-state relationships to be established for the investigated materials, highlighting non-hydrodynamic behaviour in each type of tissue over the range of investigated impact conditions. While the adipose tissue selected in this work has been shown to strengthen with impact stress in a manner similar to that seen to occur in polymeric materials, the skeletal muscle tissues exhibited a ow strength, or resistance to compression, that was independent of impact stress. Both the response of the adipose material and tested skeletal muscle tissues lie in contrast with the shock response of ballistic gelatin, which has previously been shown to exhibit hydrodynamic behaviour under equivalent loading conditions. Plate-impact experiments have also been used to investigate the shock response of a homogenized variant of one of the investigated muscle tissues. In the homogenized samples, the natural structure of skeletal muscle tissue, i.e. a fibrous and anisotropic composite, was heavily disrupted and the resulting material was milled into a fine paste. Rather than matching the response of the unaltered tissues, the datapoints generated from this type of experiment were seen to collapse back on to the hydrodynamic response predicted for skeletal muscle by its linear equation-of-state (Us = 1.72 + 1.88up). This suggests that the resistance to compression apparent in the data obtained for the virgin tissues was a direct result of the interaction of the shock with the quasi-organized structure of skeletal muscle. A soft-capture system has been developed in order to facilitate post-shock analysis of skeletal muscle tissue and to ascertain the effects of shock loading upon the structure of the material. The system was designed to deliver a one-dimensional, at-topped shock pulse to the sample prior to release. The overall design of the system was aided by use of the non-linear and explicit hydrocode ANSYSR AUTODYN. Following shock compression, sections of tissue were imaged using a transmission electron microscope (TEM). Both an auxetic-like response and large-scale disruption to the I-band/Z-disk regions within the tissue's structure were observed. Notably, these mechanisms have been noted to occur as a result of hydrostatic compression of skeletal muscle within the literature.

ng responses of the material studied were determined through planar impact experiment conducted on a single stage light-gas gun at NPS Impact Physic Lab. Impact velocities ranged from 0.2 to 0.35 km/s. The impactor material for asymmetric experiments was z-cut single crystal sapphire. Diagnostics used included a VISAR system, to measure particle velocities, PZT pins to measure onset of impact, and contact pins to measure impactor velocities and tilt angles. Through this study, dynamic loading response of ceramic Corbit-98 and ceramet tungsten carbide were determined. The Hugoniot Elastic Limit (HEL) of GC-915 was found to be 0.935 GPa and spall strength of approximately 2 GPa was also measured.

Résumé :
This work presents a systematic study of the mechanochemical processes leading to chemical reactions occurring due to effects of high-strain-rate deformation associated with uniaxial strain and uniaxial stress impact loading in highly heterogeneous metal powder-based reactive materials, specifically compacted mixtures of Ti/Al/B powders. This system was selected because of the large exothermic heat of reaction in the Ti+2B reaction, which can support the subsequent Al-combustion reaction. The unique deformation state achievable by such high-pressure loading methods can drive chemical reactions, mediated by microstructure-dependent meso-scale phenomena. Design of the next generation of multifunctional energetic structural materials (MESMs) consisting of metal-metal mixtures requires an understanding of the mechanochemical processes leading to chemical reactions under dynamic loading to properly engineer the materials. The highly heterogeneous and hierarchical microstructures inherent in compacted powder mixtures further complicate understanding of the mechanochemical origins of shock-induced reaction events due to the disparate length and time scales involved. A two-pronged approach is taken where impact experiments in both the uniaxial stress (rod-on-anvil Taylor impact experiments) and uniaxial strain (instrumented parallel-plate gas-gun experiments) load configurations are performed in conjunction with highly-resolved microstructure-based simulations replicating the experimental setup. The simulations capture the bulk response of the powder to the loading, and provide a look at the meso-scale deformation features observed under conditions of uniaxial stress or strain. Experiments under uniaxial stress loading reveal an optimal stoichiometry for Ti+2B mixtures containing up to 50% Al by volume, based on a reduced impact velocity threshold required for impact-induced reaction initiation as evidenced by observation of light emission. Uniaxial strain experiments on the Ti+2B binary mixture show possible expanded states in the powder at pressures greater than 6 GPa, consistent with the Ballotechnic hypothesis for shock-induced chemical reactions. Rise-time dispersive signatures are consistently observed under uniaxial strain loading, indicating complex compaction phenomena, which are reproducible by the meso-scale simulations. The simulations show the prevalence of shear banding and particle agglomeration in the uniaxial stress case, providing a possible rationale for the lower observed reaction threshold. Bulk shock response is captured by the uniaxial strain meso-scale simulations and is compared with PVDF stress gauge and VISAR traces to validate the simulation scheme. The simulations also reveal the meso-mechanical origins of the wave dispersion experimentally recorded by PVDF stress gauges.

Comparison of laboratory elasticity data with seismic measurements of the Earth provides a means to understand the deep interior. The effect of pressure and temperature on elastic properties must be well understood for meaningful comparisons. In this work, elastic wave velocities have been measured under shock compression to 80 GPa in an Fe-Cr-Ni alloy, to 27 GPa in polycrystalline MgO, and to 81 GPa in molybdenum preheated to 1400°C. These measurements were made by recording particle velocity histories at a sample surface using the method of velocity interferometry. In addition to elastic properties, these experiments provide information on the constitutive and equation of state (EOS) properties of the sample as well as the unloading adiabats.

Compressional and bulk wave velocities in Fe-Cr-Ni alloy are consistent with third-order finite strain theory and ultrasonic data. Thermal effects on the wave velocities are less than 2% at 80 GPa. Second pressure derivatives of velocity were constrained along the Hugoniot to be: (∂2CL/∂P2)H = -0.16 (0.06) GPa-1 and (∂2KS/∂P2)H = -0.17 (0.08) GPa-1. The measured wave profiles can be successfully reproduced by numerical simulations utilizing elastic-plastic theory modified by a Bauschinger effect and stress relaxation. Material strength was found to increase by a factor of at least 5 up to 80 GPa and to be 2-3% of the total stress.

Compressional and bulk velocities in Fe-Cr-Ni define linear velocity-density trends and can be modeled by averaging properties of Fe, Cr, and Ni. The effect of alloying ~4 wt.% Ni with Fe would change both VP and VB by less than 1% under core conditions. Compressional velocities in Fe-Ni are compatible with inner core values when corrected for thermal effects. Shear velocities in Fe, determined from a combination of VP and VB data, are ~3.6 km/s at P=150-200 GPa. Low values are most likely caused by a weak pressure dependence of the rigidity and imply that partial melting is not required in the inner core.

Wave profile and EOS measurements in polycrystalline MgO define its EOS: US = 6.77(0.08) + 1.27(0.04)up. Compressional sound velocities to 27 GPa yield the longitudinal modulus and its pressure derivative: CLo = KoS + 4/3G = 335 ± 1 GPa and C'Lo = 7.4 ± 0.2, which are in good agreement with ultrasonic determinations. The unloading wave profiles can be modeled using a modified elastic-plastic constitutive response originally developed for metals. Thermal expansivities in MgO have been determined to be 12 ± 4 x 10-6 K-1 at P=174-200 GPa and T=3100-3600 K from shock temperature and EOS data. These results imply that the lower mantle is enriched in Si and/or Fe relative to the upper mantle.

Wave profiles in molybdenum at 1400°C are the first wave profile determinations at significantly high initial temperature. The EOS determined from these measurements agrees well with previous data. The compressive yield strength of Mo is 0.79-0.94 GPa at 1400°C, and the HEL stress is 1.5-1.7 GPa. The temperature coefficient of compressional velocity, (∂Vp/∂T)p, is found to vary from -0.35(0.13) m/s/K at 12 GPa to -0.18(0.14) m/s/K at 81 GPa and compares with an ambient pressure value of -0.26 m/s/K. It is inferred that (∂Vp/∂T)p decreases with pressure, and data for Mo are shown to be consistent with trends defined by other metals.

Résumé :
We investigated dynamic response of Cu46Zr54 metallic glass under adiabatic planar shock wave loading (one-dimensional strain) with molecular dynamics simulations, including Hugoniot (shock) states, shock-induced plasticity, and spallation. The Hugoniot states are obtained up to 60 GPa along with the von Mises shear flow strengths, and the dynamic spall strengths, at different strain rates and temperatures. For the steady shock states, a clear elastic-plastic transition is identified. The local von Mises shear strain analysis is used to characterize local deformation, and the Voronoi tessellation analysis, the corresponding local structures at various stages of shock, release, tension and spallation. The plasticity in this glass, manifested as localized shear transformation zones, is of local structure rather than thermal origin, and void nucleation occurs preferentially at the highly shear-deformed regions. The Voronoi and shear strain analyses show that the atoms with different local structures are of different shear resistances that lead to shear localization. Additionally, we performed large-scale molecular dynamics simulations to investigate plasticity in Cu/Cu46Zr54 glass nanolaminates under uniaxial compression. Partial and full dislocations are observed in the Cu layers, and screw dislocations, near the amorphous−crystalline interfaces (ACIs). Shear bands are directly induced by the dislocations in the crystalline Cu layer through ACIs, and grow from the ACIs into the glass layers and absorb ambient shear transformation zones. Plasticity in the glass layers is realized via pronounced, stable shear banding. As the last part of the dissertation, we investigated with nonreactive molecular dynamics simulations, the dynamic response of phenolic resin and its carbon-nanotube (CNT) composites to shock wave compression. For phenolic resin, our simulations yielded shock states in agreement with experiments on similar polymers, except the "phase change" observed in experiments, indicating that such phase change is chemical in nature. The elastic–plastic transition is characterized by shear stress relaxation and atomic-level slip, and phenolic resin shows strong strain hardening. Shock loading of the CNT-resin composites was applied parallel or perpendicular to the CNT axis, and the composites demonstrated anisotropy in wave propagation, yield and CNT deformation. Our simulations suggested that the bulk shock response of the composites depends on the volume fraction, length ratio, impact cross-section, and geometry of the CNT components; the short CNTs in current simulations had insignificant effect on the bulk response of resin polymer.

« DEFORMATION BEHAVIOR OF A535 ALUMINUM ALLOY UNDER DIFFERENT STRAIN RATE AND TEMPERATURE CONDITIONS ». Thesis, 2014. http://hdl.handle.net/10388/ETD-2014-10-1819.

Résumé :
Aluminum alloys are a suitable substitution for heavy ferrous alloys in automobile structures. The purpose of this study was to investigate the flow stress behavior of as-cast and homogenized A535 aluminum alloy under various deformation conditions. A hot compression test of A535 alloy was performed in the temperature range of 473-673 K (200-400˚C) and strain rate range of 0.005-5 s-1 using a GleebleTM machine. Experimental data were fitted to Arrhenius-type constitutive equations to find material constants such as n, nʹ, β, A and activation energy (Q). Flow stress curves for as-cast and homogenized A535 alloy were predicted using an extended form of the Arrhenius constitutive equations. The dynamic shock load response of the alloy was studied using a split Hopkinson pressure bar (SHPB) test apparatus. The strain rate used ranged from 1400 s-1 to 2400 s-1 for as-cast and homogenized A535 alloy. The microstructures of the deformed specimens under different deformation conditions were analyzed using optical microscopy (OM) and scanning electron microscopy (SEM). Obtained true stress-true strain curves at elevated temperatures showed that the flow stress of the alloy increased by increasing the strain rate and decreasing the temperature for both as-cast and homogenized specimens. The homogenization heat treatment showed no effect on the mechanical behavior of the A535 alloy under hot deformation conditions. Hot deformation activation energy for both as-cast and homogenized A535 alloy was calculated to be 193 kJ/mol, which is higher than that for self-diffusion of pure aluminum (142 kJ/mol). The calculated stress values were compared with the measured ones and they showed good agreement by the correlation coefficient (R) of 0.997 and the average absolute relative error (AARE) of 6.5 %. The peak stress and the critical strain at the onset of thermal softening increased with strain rate for both the as-cast and homogenized A535 alloy. Homogenization heat treatment affected the high strain-rate deformation of the alloy, by increasing the peak stress and the thermal softening onset strain compared to those obtained for as-cast specimens. Deformed shear bands (DSBs) were formed in both the as-cast and homogenized A535 alloy in the strain rate range of 2000-2400 s-1.
