Abstract:
In living cells, molecular motors convert chemical energy into mechanical work. Its thermodynamic energy efficiency, i.e. the ratio of output mechanical work to input chemical energy, is usually high. However, using two-state models, we found the motion of molecular motors is loosely coupled to the chemical cycle. Only part of the input energy can be converted into mechanical work. Others are dissipated into environment during substeps without contributions to the unidirectional movement.

Abstract:
The coupling between mechanical and chemical behaviors is investigated. The Generalized Eigenstrain Method is used and enables to take easily into account several couplings, such as damage and corrosion. Modeling is then performed and compared for different configurations. Chemical reactions and diffusion effects are thus described in order to improve accuracy of such a micromechanical time-dependent model. Application is then performed on a steel reinforced concrete material. Moreover, a particular and original coupling has been introduced, which is justified by thermodynamics arguments.

Atrelado aos cenários cada vez mais complexos de extração de energia, o estudo de fenômenos acoplados em meios porosos - notadamente térmicos, hidráulicos, químicos e mecânicos - tem se apresentado como essencial na previsão de comportamento de meios geológicos no que diz respeito à disposição de rejeitos radioativos, armazenamento de dióxido de carbono, engenharia de reservatórios geotérmicos e geomecânica de reservatórios. Assim, este trabalho objetiva desenvolver um esquema de acoplamento termo-hidro-mecânico-químico iterativo visando a simulação do armazenamento geológico de dióxido de carbono, empregando um simulador de fluxo composicional (GEM) e um programa de análise de tensões (ABAQUS ou CHRONOS). A idealização das metodologias de acoplamento foi efetuada através dos processos hidro-mecânico, termo-hidro-mecânico e termo-hidro-mecânico-químico, bem como as validações e aplicações em casos reais. Os casos de validação, realizados empregando modelos simplificados monofásicos, apresentaram resultados satisfatórios quanto ao comportamento hidro-mecânico e termo-hidro-mecânico. Adicionalmente às validações, os esquemas termo-hidro-mecânico e termo-hidro-mecânico-químico foram aplicados em dois casos reais de armazenamento de CO2 apresentados na literatura, projeto In Salah (Argélia) e aquífero Utsira (Noruega), respectivamente. De maneira geral, os resultados encontrados, para ambos os casos estudados, representaram acuradamente as respostas encontradas em campo, fato que evidencia a qualidade, robustez e aplicabilidade dos esquemas de acoplamento propostos neste trabalho.
Considering the increasingly complex scenarios of energy extraction, the study of coupled phenomena in porous media - notably thermal, hydraulic, chemical and mechanical - has been considered as essential in order to predict the behavior of geological media with regard to radioactive waste storage, CO2 geological storage, geomechanics of geothermal reservoirs and reservoir geomechanics. Thus, this work aims to develop a thermo-hydro-mechanical-chemical iterative coupling scheme in order to simulate the geological storage of CO2, employing a compositional flow simulator (GEM) and a stress analysis program (ABAQUS or CHRONOS). The idealization of the coupling methodologies was carried out through the processes hydro-mechanical, thermo-hydro-mechanical and thermo-hydro-mechanical-chemical, as well as the validations and applications in real cases. The validation cases, performed employing simplified single-phase models, presented satisfactory results regarding the hydro-mechanical and thermo-hydro-mechanical behaviors. Additionally to the validations, the thermo-hydro-mechanical and thermo-hydro-mechanical-chemical schemes were applied in two real cases of CO2 geological storage reported by the literature, In Salah project (Algeria) and Utsira aquifer (Norway), respectively. In general, the results found, in both cases studied, accurately represented the behavior observed in the field, which in turn highlights the accuracy, robustness and applicability of the coupling schemes proposed in this work.

Abstract:
Ce travail de thèse se situe dans le contexte du comportement à long terme des bétons dans les stockages de déchets nucléaires. L'objectif est de modéliser le comportement couplé en compression
avec la dégradation chimique. Dans la première partie, une campagne d'essai est effectuée où la cinétique de lixiviation chimique et les propriétés mécaniques ainsi que le comportement couplé du béton sont mis en vidence. Une méthode de lixiviation accélérée est choisie qui permet de dégrader rapidement les
éprouvettes. Dans la deuxime partie, le couplage chimie - mécanique est décrit. D'une part une approche simplifiée de la lixiviation du calcium est utilisée. En tenant compte de la présence des granulats, une approche par homogénéisation utilisant
un développement asymptotique est présentée. Elle permet de décrire la tortuosité due à la morphologie, la fraction volumique des granulats ainsi qu'à la disposition des granulats.
D'autre part, plusieurs modélisations mécaniques peuvent rendre compte du comportement mécanique du béton après lixiviation. Le modèle élastoplastique endommageable permet notamment de retrouver
les déformations permanentes observées dans les essais. La résolution du problème non linéaire est réalisée dans le contexte de la méthode des éléments finis. Les simulations numériques sont comparées avec les résultats expérimentaux et montrent un bon
accord. Enfin un exemple d'application au cas d'un tunnel de stockage est présenté.

Abstract:
L'Alliage 718 est un superalliage base nickel de référence, largement utilisé dans la fabrication de composants structurels, parfois critiques, tels que les disques de turbine des turboréacteurs. Cet alliage est connu pour fortement localiser la déformation. Cette localisation peut être responsable d'un endommagement précoce en service. Pour le secteur aéronautique, les contraintes écologiques imposent une augmentation des températures de service. Il est alors essentiel d'identifier le rôle que joue le paysage de déformation à l'échelle de la microstructure sur l'endommagement assisté ou non par l'oxydation à ces températures. L'objectif premier de cette thèse est de comprendre comment la microstructure et les vitesses de chargement mécanique affectent le paysage de déformation à haute température. Le second est de lier ce paysage de déformation au comportement mécanique et aux caractéristiques de rupture observées lors d'essais de tractions à 650°C. Les travaux expérimentaux présentés dans ce manuscrit reposent principalement sur la technique de corrélation d'images numériques haute résolution qui permet de capter la réponse mécanique locale de la microstructure sur des régions statistiquement représentatives de la microstructure ; en opposition à des techniques micromécaniques plus locales. Ces travaux ont permis de montrer qu'à 650°C dans l'Alliage 718, la déformation est répartie entre les joints de grains et des bandes de glissement à l'intérieur des grains. Cette répartition dépend à la fois de la sollicitation mécanique et de la microstructure. Une taille de grains grossière favorise le glissement intragranulaire alors qu'une microstructure plus fine favorise la localisation de la déformation aux joints de grains. De même, en traction à faible vitesse de déformation, la localisation aux joints de grains est privilégiée alors qu'à plus haute vitesse de déformation et lorsque le phénomène de Portevin-Le-Chatelier a lieu, le glissement intragranulaire est majoritaire. Lors d'essais de traction sous air à 650°C, seule la localisation aux joints de grains entraine un abattement conséquent de la ductilité. Cependant, plus que l'activité plastique des joints de grains, il est montré que c'est la répartition des événements et leurs interactions qui sont responsables de la rupture intergranulaire assistée par oxydation et la perte de ductilité associée. Cette approche micromécanique associée à l'endommagement local de la matière amène un regard nouveau et intéressant sur le couplage oxydation-mécanique opérant à l'échelle de la microstructure dans cet alliage
Alloy 718 is a benchmark nickel-base superalloy, widely used in the manufacture of sometimes critical structural components, such as turbine disks in jet engines. This alloy is known to strongly localize deformation. This localization can be responsible for early damage in service. In the aeronautics sector, environmental constraints mean that service temperatures have to be increased. It is therefore essential to identify the role played by the microstructure-scale deformation landscape on oxidation-assisted or non-assisted damage at these temperatures. The primary objective of this thesis is to understand how microstructure and mechanical loading rates affect the deformation landscape at high temperatures. The second is to link this deformation landscape to the mechanical behavior and fracture characteristics observed in tensile tests at 650°C. The experimental work presented in this manuscript is based mainly on the high-resolution digital image correlation technique, which captures the local mechanical response of the microstructure over statistically representative regions of the microstructure; as opposed to more local micromechanical techniques. This work has shown that at 650°C in Alloy 718, deformation is distributed between grain boundaries and slip bands within the grains. This distribution depends on both mechanical stress and microstructure. A coarse grain size favors intragranular slip, while a finer microstructure favors localization of deformation at grain boundaries. Similarly, at low strain rates, localization at grain boundaries is favored, whereas at higher strain rates and when the Portevin-Le-Chatelier phenomenon occurs, intragranular slip is predominant. In tensile tests in air at 650°C, only localization at grain boundaries results in a significant reduction in ductility. However, more than the plastic activity of grain boundaries, it has been shown that it is the distribution of events and their interactions that are responsible for oxidation-assisted intergranular fracture and the associated loss of ductility. This micromechanical approach, combined with local material damage, provides an interesting new insight into the oxidation-mechanical coupling operating at the microstructural scale in this alloy

Dummy metal insertion is one of the latest methods to be commonly used in the post-layout step during design implementation. It is used to keep the metal den- sity within the chip area at a constant value and reduce the variation in thickness of chemical-mechanical planarization (CMP) [5]. During metal fill insertion, the gradient of metal density should be also considered to ensure that the density vari- ation is not above a threshold within a sliding window. This threshold is typically recommended by foundry [29]. However, the coupling capacitance is significantly increased by dummy metal insertion, and the increased coupling capacitance may cause timing failure in the chip''s performance. This thesis proposes one metal fill insertion design flow and two algorithms, greedy and force-directed, for inserting the 45-degree metal fills (diagonal fills). The design flow includes three stages: the design preparation stage, the dummy fill region extraction stage and the dummy fill insertion stage. The force-directed algorithm which is applied in the dummy fill in- sertion stage considers the coupling capacitance as a weight and avoids the impact of the timing slack. Diagonal metal fills are simulated and it is concluded that they have less capacitance than 0-degree metal fills (parallel fills) and 90-degree metal fills (per- pendicular fills). Compared with 0- and 90-degree metal fills, 45-degree metal fills could reduce capacitance by 1.9%{14.1%. TNS (total negative slack) and WNS (worst negative slack) [22] are also maintained with 45-degree metal fills, whereas 0- and 90-degree metal fills increase the timing delay from 13 pico-seconds in ex- perimental test case of design3 [9] to 344 pico-seconds in experimental test case of design6. Design3 is the design with clock cycle of 2000 pico-seconds, whereas design6 is the design with clock cycle of 14000 pico-seconds. Experimental results based on commercial tools demonstrate that our proposed force-directed methods can decrease the coupling capacitance and improve timing performance.

Abstract:
Extreme climate change and demanding energy resources have led to new geotechnical engineering challenges critical for sustainable development and resilient infrastructure of our society. Applications such as geological disposal of nuclear waste and carbon dioxide, artificial ground freezing, and hydraulic fractures all require an in-depth understanding of the thermo-hydro-mechanical coupling mechanisms of geomaterials subjected to various environmental impact. This dissertation presents a multiphysical computational framework dedicated to address the issues related to those unconventional applications. Our objective is not only incorporating multiphysical coupling effects at the constitutive laws, but also taking into account the nonlocal effects originated from the flow of pore-fluid, thermal convection and diffusion among solid and fluid constituents, and crystallization and recrystallization of crystals in the pore space across length scales. By considering these coupling mechanisms, we introduce a single unified model capable of predicting complex thermo-hydro-mechanical responses of geological and porous media across wide spectra of temperature, confining pressure and loading rate. This modeling framework applies to two applications, i.e., the freezing and thawing of frozen soil and the modeling of anisotropic crystal plasticity/fracture response of rock salt. Highlights of the key ingredients of the models cover the stabilization procedure used for the multi-field finite element, the return mapping algorithm for crystal plasticity, the micromorphic regularization of the Modified Cam-Clay model, and the strategy for enhancing computational efficiency of solvers, such as pre-conditioner, adaptive meshing, and internal variable mapping. By introducing the multiphysical coupling mechanisms explicitly, our computational geomechanics model is able to deliver more accurate and consistent results without introducing a significant amount of additional material parameters. In a parallel effort, we analyze the impact of thermo-hydro-mechanical (THM) coupling effects on the dynamic wave propagation and strain localization in a fully saturated softening porous medium. The investigation starts with deriving the characteristic polynomial corresponding to the governing equations of the THM system. The theoretical analysis based on the Abel–Ruffini theorem reveals that the roots of the characteristic polynomial for the THM problem cannot be expressed algebraically. Our analysis concludes that the rate-dependence introduced by multiphysical coupling may not regularize the THM governing equations when softening occurs.

This study addresses three major parts: (1) to establish the technology for the preparation of tubular ceramic membrane substrates; (2) to establish the technology for the preparation of tubular carbon/ceramic membranes; and (3) to reclaim water from chemical mechanical polishing (CMP) wastewaters by a combined treatment system of a novel simultaneous electrocoagulation/electrofiltration (EC/EF) process coupled with laboratory-prepared tubular composite membranes (TCMs) and evaluate its feasibility of water recycling and operating cost. First, in this work the green substrates of tubular porous ceramic membranes consisting of corn starch were prepared using the extrusion method, followed by curing, drying, and sintering processes. Experimental results have demonstrated that an addition of starch granules to the raw materials would increase the porosity, pore size, and permeability of the sintered matrices but accompanied by a decrease of the compressive strength. It revealed that the membrane substrates with desired pore sizes and permeability could be obtained by adding a proper amount of corn starch. The nominal pore sizes of the prepared membrane substrates were ranging from 1 to 2 μm. The membrane substrates thus obtained are suitable for crossflow microfiltration applications. Second, the carbon/alumina TCMs and carbon fibers/carbon/alumina TCMs were obtained by the chemical vapor deposition (CVD) method resulting in a pore size distribution of 2 to 20 nm and a nominal pore size ranging from 3 to 4 nm. Besides, during the CVD process the reaction temperature was found to be the main factor for influencing the pore size of carbon fibers/carbon/alumina TCMs and the type of carbon fibers. When the reaction temperature was above or equal to 1000 ℃, the pore size of TCMs increased due to the pyrolysis of thin carbon layers. The “Tip-Growth” mechanism was found for tubular carbon fibers formation under such conditions. On the other hand, “Base-Growth” (also known as “Root-Growth”) mechanism was found for curved and irregular carbon fibers formation when reaction temperature was under or equal to 950 ℃. Third, for reclaiming water from CMP wastewaters, experimental results of laboratory-prepared carbon/alumina TCMs incorporated into the custom-made EC/EF treatment module used was found to be capable of treating oxide-CMP wastewater in a proper manner. Permeate thus obtained had a turbidity of below 0.5 NTU and the removal efficiencies of TS (total solids content) and Si were 80% and 93 %, respectively. Further, for understanding the applicability of fractional factorial design and Taguchi experimental design, two laboratory-prepared carbon fibers/carbon/alumina TCMs (i.e., Tube B and Tube E obtained from two different preparation conditions) incorporated into the EC/EF treatment module were chosen for evaluating the performance of CMP wastewaters treatment. Permeate obtained based on the fractional factorial design of experiments had a turbidity of below 1.0 NTU and the removal efficiencies of TOC (total organic carbon), Cu and Si were all above 80 % except for the TS (i.e., ranging from 72 to 74%). Permeate obtained based on the Taguchi experimental design had a turbidity of below 0.3 NTU and the removal efficiencies of TS, TOC, Cu and Si were ranging from 82 to 91%. Apparently, similar optimum operating conditions were obtained from the fractional factorial design and Taguchi experimental design. Permeate thus obtained could be reused as the make-up water of cooling towers. The operating cost of Cu-CMP wastewater treatment based on a total water reclaim of 600 m3 per day was determined to be NT$ 98 (i.e., US$ 3.22) and NT$ 35 (i.e., US$ 1.05) per m3 of permeate for Case 1 (i.e., the filtration area of 0.0189 m2 in one EC/EF module) and Case 2 (i.e., the filtration area of 0.0801 m2 in one EC/EF module), respectively.

Abstract:
The work presents the results of an intense experimental research into the chemo-mechanical coupling phenomena involving the sediments from the Mar Piccolo basin (Taranto, South of Italy), severely contaminated by both heavy metals (e.g. Hg, Pb, Cd, Cu and Zn) and organic pollutants (PCBs, PAHs, and dioxins). Among the different matrices involved in the environmental studies, i.e. sediments, water and biota, this research focuses on the submarine sediments and reports the results of both the chemical and the geotechnical investigations carried out during the off-shore campaign, prompted by the Special Commissioner for urgent measures of reclamation, environmental improvement and redevelopment of Taranto. Geotechnical tests were carried out on more than 50 samples, taken from up to 30 m below the seafloor. The standard equipment and procedures were properly adapted to take into account the influence of salt and organic compounds in the pore fluid. The geotechnical testing programme included tests aiming to characterise physical properties, composition and state of the sediments, oedometer tests to determine the 1D compression and consolidation properties of the soil and CIU triaxial tests for the measurements of both isotropic compressibility and strength. Furthermore, an apparatus was developed for both the squeezing of the sediment and the pore flid extraction of pore fluid during compression. Off-shore piezocone tests were also carried out and the results were used to interpret the stratigraphy and derive engineering properties of soils. The integration of the geotechnical and chemical data allowed to investigate the effects of the chemo-mechanical interaction processes on the geotechnical behaviour of the sediments, in the light of the most relevant literature. The Mar Piccolo represents a “natural laboratory” and an emblematic case in the worldwide panorama of polluted sites. Hence, the study offered the possibility to produce and analyse an uncommon coupled database of both geotechnical and chemical results concerning natural geomaterials altered by the presence of different sources of contamination.

Abstract:
ABSTRACT: Underground coal pyrolysis (UCP) represents an environmentally friendly approach to exploiting coal resources through in-situ conversion, with its efficacy hinging on the efficient flow of gas through porous media. Consequently, the study of flow behavior, particularly permeability characteristics, holds significant importance for UCP. While the strength characteristics in thermal environments have been extensively researched, the reaction-dependent structural evolution remains relatively unexplored, despite its crucial role in reservoir stability and gas flow optimization. In this study, initially, permeability tests were conducted on coal samples after heating. Subsequently, the microscopic structures of the heated coal samples were observed using a scanning electron microscope (SEM). Lastly, a model incorporating thermal, mechanical, and chemical coupling effects was developed. The key findings reveal that the pyrolysis process can be categorized into three distinct stages based on temperature thresholds, including drying (100-300°C), medium-temperature pyrolysis (300-600°C), and high-temperature pyrolysis (600-1000°C). Additionally, the microstructural alterations that occur during the reaction are highly dependent on temperature, particularly above 350°C. These microstructural changes further influence the permeability characteristics of the samples. After reaching a temperature of 300°C, numerous new pores and microscopic fractures emerge within the sample model. Taking into account the impact of chemical reactions, the evolution of the microscopic structure influences the overall strength of the coal model through processes such as depolymerization and polycondensation during pyrolysis. 1 INTRODCTION Underground coal gasification is the direct controlled combustion of underground coal, extraction of energy-containing components in coal, ash and residue left underground. Compared with traditional coal mining, coal underground gasification technology is more beneficial to realize the low-carbon utilization of coal. The whole process is the result of multi-field coupling, involving heat transfer, solid deformation and gas flow. The underground coal gasification space is large, the combustion height is large, the temperature is high, and the roof and floor are also affected by high temperature. Underground coal gasification is of great strategic significance to the development of natural gas in China, and it is a new strategic way to effectively supply methane and hydrogen with Chinese characteristics. The physical and mechanical properties of coal rock and roof and floor rock in different blocks are very discrete and closely related to rock facies. In the process of coal gasification, the physical and mechanical properties of coal and rock are strongly affected by temperature. The design and optimization of coal gasification construction parameters involves the numerical simulation of underground coal gasification process, which requires the physical and mechanical property parameters and evolution laws of coal and rock.

Abstract:
ABSTRACT The complex coupling interaction phenomena among rock mechanics, fluid flow, heat transfer and geochemical reactions has become a critical topic in complex subsurface systems including the production of unconventional oil and gas. In this paper, we introduce a fully coupled Thermo-Hydro-Mechanical-Chemical (THMC) framework that is being developed at Los Alamos National Laboratory (LANL). The framework integrates four LANL-developed codes: HOSS, Amanzi, dfnWorks and InyanCC. HOSS simulates deformation of the rock matrix as well as the opening, closing and shear sliding in the discrete fractures (mechanics), while Amanzi solves subsurface multiphase flow and reactive transport, dfnWorks generates meshes with complex discrete fracture networks, and InyanCC links the mechanics and flow solvers while controlling the whole simulation processes. The advantages of this coupling framework are: 1) it is based on hybrid continuum-discontinuum approaches which overcomes the limitations seen with pure continuum assumptions; 2) both mechanics and subsurface flow solvers are fully parallelized for distributed memory systems which allows the users to simulate large scale problems on HPC clusters. Different selected benchmarking problems are simulated using this THMC framework. The results show good agreement with the analytical solutions, which verifies the accuracy of the framework. INTRODUCTION Current applications of geotechnical engineering and geo-energy in the subsurface rely significantly on complex coupling process among rock mechanics, fluid flow, heat transfer and geochemical reactions, including geothermal production, unconventional oil and gas production and underground nuclear explosions. Hence, Modeling Thermo-Hydro-Mechanical-Chemical (THMC) processes is essential in understanding the coupled processes in subsurface geological media. Fully addressing the computational challenge of coupled THMC process simulation has been exacerbated by the inability to simulate coupled processes in both the rock matrix and discrete fractures. However, modern subsurface simulators taking advantage of the high-performance computation have been proposed to overcome these challenging problems. Cheng, 2016; Rutqvist et al., 2001; and Wang, 2000 proposed different approaches for modeling the evolution of pressure, stress, and temperature fields in porous media, including equations for pressure diffusion, mechanical equilibrium, and energy transport. Rutqvist and Stephansson (2003) introduced a coupled THM model based on sub-grid scale fracture networks. Min and Jing (2003) reported numerical simulations of hydro-mechanical coupling in fracture networks. These models capture the contribution of discrete fracture deformation to permeability anisotropy through the effective properties such as permeability and porosity. However, these methods have limitation in modeling time-evolving large scale THM system when the characteristic length of network structures is much larger than the grid block scale.

Abstract:
Abstract Characterization of the non-linear biaxial mechanical properties of chemically treated bovine pericardium (BP) is necessary of proper bioprosthetic heart valve design. New chemical treatment technologies such as photo-oxidation (Moore, et al., 1994), whose aim is to reduce calcification, produce new biomaterials with unknown mechanical behaviors. Further, the state of tension during fixation can profoundly affect the mechanical properties chemically treated BP. In this work we performed biaxial mechanical testing on free-fixed glutaraldehyde treated BP and photo-oxidized tissue that was free-fixed and pre-stretched during fixation. BP biaxial mechanical behavior was modeled using an exponential strain energy function. This strain energy function allowed comparisons of the coupling responses using the globally derived material constants.

Abstract:
The extracellular matrix (ECM) is an important cellular component that provides structural support for cells that form the various connective tissues in the body and has been linked to various important cellular processes. One major, ubiquitously expressed ECM protein, fibronectin (FN) has been well documented to play an important role in the ECM, but most studies have investigated FN and its assembly and structural organization mainly through chemical stimulation. The ECM though likely experiences multiple modes of stimulation such as mechanical and chemical inputs. Since cells and the ECM may experience mechanical and chemical stimulation, we examined how NIH 3T3 fibroblasts altered their ECM in response to applied mechanical and chemical stimulation. Mechanical stimulation revealed an increase in FN matrix formation and secretion as reflected by immunofluorescence as well as FN localization around the cell periphery. Coupling of mechanical stimulation with chemical stimulation via inhibition of Rho activity revealed the same behavior as cells exposed purely to mechanical stimulation. This study is among the first to show the effect of coupled modes of stimulation on the ECM and show a purely mechanics-induced stimulation of ECM formation. These results have implications in a variety of fields including mechanotransduction, biophysics and bioengineering.
