Abstract:
Slope stability analyses are performed mostly as a two-dimensional (2D) section under the assumption of plane strain conditions, without much consideration to the impact of three-dimensional (3D) shapes. For natural slopes that have the complexities of slope surfaces, 3D modeling may also be considered since it can represent the more realistic geometry of the slope. However, previous studies show that the factor of safety (FS) as a result of 3D analyses mostly overestimated the FS from 2D analyses. This may lead to a long discussion on whether the 3D analysis is still applicable for the natural slopes, and could it represent the same results as the 2D analysis. This study was conducted using the finite element method for calculating the 2D and 3D FS of Pasir Muncang natural slope in order to observe differences of FS resulted from both analyses. A comparison of the FS from the 2D and 3D analyses, and also verification of sensitivity on several factors that impact the 2D and 3D models have been performed. The results of this study has indicated that some factors such as soil parameters, contour interval, and mesh coarseness greatly affect the results of the 2D and 3D calculations. Having carefully selected the aforementioned factors as the inputs for calculations, the difference between the FS values of 3D and 2D analyses becomes smaller. The final result of FS for this case study from the 3D analysis was still higher than the one from the 2D analysis, with the ratio of FS from 3D to FS from 2D was 1.44. It can be inferred that the use of 3D analyses needs more accurate data selections compared to the 2D analyses.

Abstract:
As the usage of both BIM (Building Information Modelling) and 3D-GIS (Three-Dimensional Geographic Information Systems) has increased within the field of urban development and construction, so has the interest in connecting these two tools.  One possibility of integration is the potential of visualising BIM models together with other spatial data in 3D. Another is to be able to perform spatial 3D analyses on the models. Both of these can be achieved through use of GIS software. This study explores how integration of BIM and GIS could look. The goal was to perform typical GIS analyses in 3D on BIM models. Previous research points towards some success within the field through use of the indicated standard format for each tool – IFC (Industry Foundation Classes) for BIM and CityGML (City Geographic Markup Language) for GIS. Transformation between the formats took place through use of the BIM software Revit, the transformation tool FME and the GIS software ArcGIS. A couple of reviewed applications of GIS analyses were chosen for testing on the converted models – indoor network analysis, visibility analysis and spatial analysis for 3D buildings. The input data in the study was several BIM models, both models created for real-life usage and others that only function as sample data within the different software. From the results of the practical work it can be concluded that a simple, automated and full-scale integration does not seem to be within reach quite yet. Most transformations between IFC and CityGML failed to some extent, especially the more detailed and complex ones. In some test cases, the file could not be imported into ArcGIS and in others geometries were missing or existing even though they should not. There were also examples where geometries had been moved during the process. As a consequence of these problems, most analyses failed or did not give meaningful results. A few of the original analyses did give positive results. Combining (flawed) CityGML models with other spatial data for visualisation purposes worked rather well. Both the shadow volume and sightline analyses did also get reasonable results which indicates that there might be a future for those applications. The obstacles for a full-scale integration identified during the work were divided into four different categories. The first is BIM usage and routines where created models need to be of high quality if the final results are to be correct. The second are problems concerning the level of detail, especially the lack of common definitions for the amount of details and information. The third category concerns the connection between local and global coordinate systems where a solution in form of updates to IFC might already be in place. The fourth, and largest, category contains those surrounding the different formats and software used. Here, focus should lie on the transformation between IFC and CityGML. There are plenty of possible, future, work concerning these different problems. There is also potential in developing own tools for integration or performing different analyses than those chosen for this thesis.
I takt med den ökade användningen av både BIM och 3D-GIS inom samhällsbyggnadsprocessen har även intresset för att sammanföra de två verktygen blivit större. En möjlighet med integration är potentialen att visualisera BIM-modeller tillsammans med andra geografiska data i 3D. En annan är att kunna genomföra rumsliga 3D-analyser på modellerna. Båda dessa går att utföra med hjälp av GIS-programvara. Denna studie utforskar hur en integration mellan BIM och GIS kan se ut. Målet är att genomföra typiska GIS-analyser i 3D på BIM-modeller. Tidigare forskning pekar mot vissa framgångar inom området genom att arbeta med det utpekade standardformatet för respektive verktyg – IFC för BIM och CityGML för GIS. Transformation mellan formaten skedde med hjälp av programvarorna Revit, FME och ArcGIS. Ett par framhållna tillämpningar av GIS-analyser valdes ut för tester på de konverterade modellerna – nätverksanalyser inomhus, siktanalyser och rumsliga analyser för 3D-byggnader. Som indata användes flera olika BIM-modeller, både sådana som tillverkats för faktisk användning och modeller som skapats för att användas som exempeldata inom programvarorna. Utifrån resultaten från det praktiska arbetet kan konstateras att en enkel, automatiserad och fullskalig integration mellan verktygen verkar ligga en bit in i framtiden. De flesta transformationerna mellan IFC och CityGML misslyckades i någon aspekt, speciellt de mer detaljerade och komplexa. I vissa testfall kunde filen inte importeras i ArcGIS, i andra saknas eller existerar oväntade geometrier även om importen lyckats. Det finns också exempel där geometrier förflyttats. Som en konsekvens av dessa problem kunde de flesta 3D-analyser inte genomföras alls eller lyckades inte ge betydelsefulla resultat. Ett fåtal av de ursprungliga analyserna gav dock positiv utdelning. Att kombinera (felaktiga) CityGML-modeller med annan rumslig data fungerade förhållandevis väl ur ett visualiseringssyfte. Både skuggvolymsanalysen och framtagandet av siktlinjer från byggnaderna gav någorlunda korrekta resultat vilket indikerar att det kan finnas en framtid gällande de tillämpningarna. Hindren för en fullskalig integration som identifierades genom arbetet delades upp i fyra olika kategorier. Den första är BIM-användning där hög kvalitet på de skapade modellerna är viktigt för korrekta slutresultat. Den andra är detaljeringsgraden där avsaknaden av gemensamma definitioner för detaljeringsgraderna ställer till problem. Den tredje kategorin är koordinat- och referenssystem där en lösning på kopplingen mellan lokala och globala system redan kan finnas på plats i en av de senare utgåvorna av IFC-formatet. Den sista och största kategorin är problematiken kring just format och programvaror där mer arbete på översättningen mellan IFC och CityGML kommer att krävas. I framtiden finns det gott om arbete att göra med dessa olika problem. Det finns också potential att utveckla egna verktyg för integrationen eller att ägna sig åt att göra andra analyser än de som valdes ut i den här studien.

Ainda hoje a animação de caracteres tridimensionais é um processo manual. Aplicações como jogos de computadores, ou capturas de movimentos para efeitos especiais em filmes requerem incessante intervenções do artista, que praticamente guia os movimentos a cada passo. Nesses exemplos as ferramentas disponíveis oferecem geralmente edição de detalhes, ou no espaço ou no tempo. Essa tese utiliza duas abordagens analíticas ao processo de animação: harmônica e modal, permitindo descrever movimentos com poucos controles. O resultado destas animações é mostrado em tempo real para o usuário graças às suas implementações na GPU. Em particular, permite escolher os parâmetros de controle através de galerias animadas em tempo real ou ainda usar as freqüências da música para guiar a animação.
Animation of three-dimensional characters is still a mostly manual process. Applications such as computer games and motion capture for special effects in movies require continuous intervention from the artist, who needs to guide the movement almost step by step. In such examples the available tools provide controls mainly over local details, either in space or in time. This thesis uses two analytical frameworks to deal with the process of animation: harmonic and modal analyses, allowing the description of movements with a reduced set of controls. A GPU implementation of the resulting animations allows for real-time rendering of those. In particular, it allows applications such as interactive control tuning through design galleries animated in real-time or three-dimensional music visualization. Particularly, it allows the choice of control parameters through the use of animated galleries in realtime and the use of music frequencies to guide the animation.

Abstract:
The purpose is to compare the 2D and 3D analysis methodologies in investigating the performance of a Concrete Faced Rockfill Dam (CFRD) under static and dynamic loading conditions. Ç
okal Dam is the case study which is a CFRD located in northwest Turkey at the Thracian Peninsula. Rockfill interface and faceplate were simulated as nonlinear modulus of elasticity, detailed nonlinear tractive behavior and total strain rotating crack model, respectively. These behaviors were calibrated to define the exact behavior by detailed material tests. The analyses that cannot be done by 2D analyses, such as stress, crack width distribution along the face slab are conducted by 3D analyses to determine the necessity of these outcomes. Since effect of valley ends cannot be produced by 2D analyses, it is necessary to check 3D analyses to ensure liability of the results. Another comparison between detailed analysis of 2D models and linear elastic 2D models were covered to get practical and industrial solutions for the guiding methods of CFRDs for preliminary designs in this study.

Abstract:
Le sujet de cette thèse concerne les études structurales d'une nouvelle génération d'oligomères, les foldamères, construits à partir de mimes pseudopeptidiques capables d'adopter des structures secondaires déterminées. Trois familles d'oligomères ont été étudiées. Plusieurs méthodes spectroscopiques ont été à chaque fois employées couplées à la modélisation moléculaire, afin de caractériser les propriétés structurales des foldamères. La première famille a été synthétisée par le groupe de Muriel Amblard et Monique Calmès de l'IBMM à Montpellier. Nous avons évalué les propriétés à se structurer du motif (S)-ABOC. Plusieurs oligomères de tailles variables ont été synthétisés et nous avons montré le motif (S)ABOC lorsqu'il est introduit dans une séquence peptidique est capable de générer des coudes beta. L'enchaînement de ces coudes conduits à la formation d'hélices qui en fonction des motifs pseudo-peptidiques associés présentent des caractéristiques différentes. La seconde famille étudiée comprenait des oligomères formés à partir de monomères contraints de type thiazole. Nous avons montré que ce motif, développé par Ludovic Maillard à l'IBMM à Montpellier forme des pseudocycles en C9 qui s'organisent ensuite en une hélice qui est observable dès le tétramère. La troisième famille d‘oligomères étudiée est issue du LCPM. Elle comprend des oligomères alternant des acides alpha-aminés et des acides aminés de type aza dans lesquels le carbone alpha a été remplacé par un atome d'azote. Nous avons montré que le motif aza induit un repliement en coude beta facilitant la cyclisation de la molécule. Dans ma thèse nous avons caractérisé les propriétés à s'auto-structurer de trois familles de foldamères pseudopeptidiques en combinant les résultats expérimentaux issus de la résonance magnétique nucléaire, la spectroscopie infrarouge, le dichroïsme circulaire et la diffraction des rayons X et en les intégrant à des calculs de modélisation moléculaire. Notre étude répertorie les propriétés de chaque motif à former des éléments de structure secondaire et à induire la formation de foldamères
The subject of this thesis deals with the structural studies of a new generation of oligomers, so called foldamers, constructed from pseudopeptidic mimics and able to adopt determined secondary structures. Three families of oligomers were investigated. For each oligomer several spectroscopic methods have been used combined with molecular modeling in order to characterize their structural properties. The first family was studied in collaration with the group of Muriel Amblard and Monique Calmès at IBMM in Montpellier. We have evaluated the structural properties of the motif (S)-ABOC. Several oligomers of varying sizes were synthesized and we have shown that the pattern (S)-ABOC, when introduced into a peptide sequence, is capable of generating beta turn. The sequence of these turn leads to the formation of helices, which, according to associated pseudo-peptide patterns shows different characteristics. The second project discussed the conformation of oligomers family formed from constrainted thiazole monomers. We have shown that this pattern developed by Ludovic Maillard at IBMM in Montpellier adopted pseudocycles C9 which led to helices. THis property was observed starting from the tetramer. The third family of oligomers comes from the LCPM, alternating oligomers of alpha amino acids and aza amino acids, in which the alpha carbon has been replaced by a nitrogen atom. We showed that the pattern aza induces folding of the beta turn, facilitating the cyclization of the molecule. In this thesis we have characterized the properties to self-structuring of three families of pseudopeptide foldamers by combining experimental results from nuclear magnetic resonance, infrared spectroscopy, circular dichroism and X-ray diffraction combined with molecular modeling calculations. Our study lists the properties of each pattern to form secondary structure elements and to induce the formation of foldamers

Abstract:
Afin d'optimiser les performances des circuits intégrés, l’industrie de la micro et nanotechnologie mène d'intenses recherches sur la miniaturisation à l'échelle sub-22nm de leurs principaux constituants que sont les transistors MOS. La réduction de la taille de grille atteint néanmoins des limites qui rendent problématique le contrôle du canal. L'une des approches les plus prometteuses pour contourner ce dilemme et ainsi poursuivre la miniaturisation des futurs nœuds technologiques, consiste au développement des transistors d’architectures 3D (Trigate ou FinFET). La mise au point de telles structures requiert une caractérisation de plus en plus fine, surtout à une étape clé de leur élaboration, qui est celle du dopage par implantation ionique. Du fait des faibles profondeurs implantées, l'analyse par diffusion d'ions de moyenne énergie (MEIS) est tout à fait adaptée pour quantifier les implants et évaluer la conformité du dopage grâce à sa bonne résolution en profondeur (0.25 nm). Néanmoins, les dimensions de la sonde (0.5 × 1 mm2) étant très supérieures à celles des motifs, il nous a fallu développer un protocole d’analyse propre à de telles architectures. Les échantillons étudiés dans le cadre de cette thèse sont des systèmes modèles. Ils sont constitués de réseaux de lignes de silicium (Si) 3D, formées par gravure lithographique par faisceaux d’électrons (e-beam) sur des plaques 300 mm de types silicium sur isolant (SOI). Le dopage a été réalisé à une énergie de 3 keV par implantions conventionnelle (ou beam line) et immersion plasma (PIII).L’analyse des spectres MEIS des implants insérés dans chaque facette des motifs a été possible grâce aux simulations 3D types Monte-Carlo effectuées avec le logiciel PowerMEIS. Nous avons ainsi développé une nouvelle méthode adaptée à la caractérisation du dopage 3D. Les mesures ont montré que, contrairement à la méthode PIII, la dose implantée par la méthode conventionnelle correspond à celle visée. Cependant la distribution des dopants introduits au sein des nanostructures par les deux méthodes de dopage n’est pas uniforme. Dans les échantillons implantés par PIII, on a observé une importante concentration des dopants aux sommets des motifs et un faible dopage des flancs. Ceci étant moins marqué dans celui implanté par la méthode conventionnelle. En corrélant les techniques de Microscopie Electronique en Transmission (MET), d’analyses par rayons x synchrotron et MEIS, nous avons également pu déterminer les dimensions des zones implantées ainsi que celles des zones cristallines dans les réseaux de lignes gravées.L'exploitation de la technique MEIS en mode canalisation a permis une évaluation complète des couches non gravées. L’investigation des endommagements post – dopage dans les régions cristallines non implantées ont été menées toujours avec la même technique MEIS. Les résultats ont révélé une importante influence de la méthode d’implantation et la température sur les défauts et les déformations dans le cristal. L’origine des anomalies au sein des échantillons a ainsi été identifiée en corrélant les mesures MEIS et celles par spectrométrie de masse des ions secondaires en temps de vol (ToF-SIMS)
With the aim of optimizing the performances of integrated circuits (ICs), the nanotechnology industry is carrying out intense research activities on the miniaturization at the sub-22 nm scale of their main constituents: the MOS transistors. Nevertheless, the shrinking of the gate size has reached the limits that make the control of the channel problematic. One of the most promising approaches to circumvent this dilemma and thus further the miniaturization of the future technological nodes, is the development of transistors of 3D architecture (Trigate or FinFET). The elaboration of such nanostructures requires increasingly fine characterization tools precisely at a key stage of their fabrication, namely the ion implantation doping. Given the ultra-shallow implantation depths, the medium energy ion scattering (MEIS) analysis technique is suitable for quantifying the implants and evaluating the doping conformity thanks to its good depth resolution (0.25 nm). However, the dimensions of the beam (0.5×1 mm2) being by far larger than those of the patterns, we had to develop an analysis protocol dedicated to such architectures. The samples studied in the framework of this thesis are considered as model systems. They are constituted of 3D silicon (Si) Fin – shaped line gratings, etched on the 300 mm wafers of silicon on insulator (SOI) types by using the electron beam (e-beam) lithography. The doping has been carried out at an energy of 3 keV by using the conventional (or beam line) and plasma immersion ion implantation (PIII) methods.The analyses s of the MEIS spectra of the dopants implanted into each part of the patterns were possible thanks to the 3D Monte-Carlo simulations performed with the PowerMEIS software. We have thus developed a new method suitable for the characterization of the 3D doping. The measurements have shown that, contrarily to the PIII method, the dose implanted by the conventional method is as targeted. However, the distribution of the dopants inserted within the nanostructures by using the two doping methods is not uniform. In the PIII implanted samples, a large dopants' focusing at the tops of the patterns and low sidewalls' doping have been observed. This is less marked in the one implanted by the conventional method. By correlating the Transmission Electron Microscopy (TEM), synchrotron x – ray analyses and MEIS, we have also determined the dimensions of the implanted and crystal areas of the line gratings.The exploitation of the MEIS technique in channeling mode has permitted the full assessment of the impacts of the implantation in the non-etched layers. The investigations of the crystal qualities in the non-implanted areas were carried out with the same technique. The results show that the temperature conditions have a considerable influence on the defects and lattice deformations. The origin of the anomalies in the samples has thus been identified by correlating the MEIS and Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) measurements

Abstract:
In gas turbines, the temperature behind the combustors is the highest, meaning that the blades in the first stage of the turbine require cooling air. This makes the structural blade model very detailed due to the presence of the cooling pattern. For aeromechanical design, one of the first steps is to perform a modal frequency check by using 3d Finite Element models and the Campbell diagram to establish if the design is acceptable with respect to resonance margins. If the 3d detailed geometry (including all the cooling details) is used the model becomes extremely large. In order to perform various loops between structural dynamics and aerodynamics in an early stage, the dynamic model of cooled blades should be simplified. The simplified model should be accurate enough in terms of predicting correct frequencies but much lighter in size.   The objective of this thesis is to perform parametric studies of different 3d simplified cooled turbine blade models. Various models with different geometrical features are created from the history of the CAD software (NX). Different FE meshes are produced in the Hypermesh software and the modal analyses are solved in Abaqus. The results are compared with the fully detailed model. The influence of the cooling features for each test case is summarized and this will be useful for creating reduced order models. Explanation and guidelines with respect to the mesh generation and loading conditions in Hypermesh software are also included in the appendix section.    For quick frequency checks during the intial stages of the design, the solid blade model can be used which has the modal frequencies within 10 percent range from the fully detailed model. The cooling core features that are important with respect to dynamics are cooling matrix, the ribs and the trailing edge cutback which contribute to the stiffness of the blade.

Les anticorps sont les nouveaux blockbusters au niveau des médicaments. Les anticorps de camélidés, à savoir les domaines VHH, constituent la prochaine génération de traitements et de diagnostics basés sur les anticorps. Pour améliorer nos connaissances sur ces VHH, il est essentiel d'avoir une meilleure vision de la relation séquence, structure et dynamique de ces protéines, et ceci afin d'améliorer leur affinité et leur stabilité. Dans une première étape, une analyse en profondeur des séquences et de la structure des VHHs est effectuée à l'aide d'approches classiques, mais également d'un alphabet structural appelé Blocs Protéiques. Dans une deuxième étape, la relation séquence-structure de ces domaines est évaluée en examinant le lien entre séquences et structures. Dans une troisième étape, la spécificité et la difficulté d’obtenir des modèles structuraux pertinents sont soulignées avec différentes approches, donnant des résultats inattendus. Ensuite, des simulations dynamiques moléculaires à grande échelle ont été effectuées et ont montré une grande diversité dans les comportements de la dynamique des domaines VHH. Enfin, nous terminons notre thèse en énumérant les principales conclusions des chapitres précédents et des perspectives futures
Antibodies are the new blockbusters for drug design. Camelid antibodies, namely VHH domains are projected to be the next generation therapeutics and diagnostics. To improve our knowledge on VHHs, it is essential to have a better view on the sequence, structure and dynamics relationships to improve their affinity and stability. In a first-step a deep analysis of the sequence and the structure of VHHs are done using classical approaches, but also a structural alphabet named Protein Blocks. In a second step, the sequence-structure relationship of these domains is assessed looking at diverse sequence and structures conservations. In a third step, the specificity and difficulty to obtain pertinent structural models are underlined using different approaches, showing unexpected results. Next, the largest scale Molecular dynamic simulations of VHH had been done and shown a large variety in the behaviours of VHH domains dynamics. Finally, the thesis is wrapped up listing significant conclusions from the above chapters and with future perspectives

This thesis tackles two main problems in stratospheric modelling. First, the accuracy of the stratospheric transport provided by meteorological analyses, which is crucial for off-line chemistry transport models (CTMs) to produce accurate distions of tracers. Second, the description of stratospheric radiatively active gases included in numerical weather prediction (NVVP) general circulation models (GCMs), which in many cases is too simple for current stratospheric purposes.

Abstract:
La microstructure de l'émail est étudiée depuis longtemps, mais ses modalités de formation sont encore floues. J'ai employé une approche multi-disciplinaire alliant paléontologie et biologie cellulaire dans une perspective évolution-développement afin de parvenir à une vision intégrée et en profondeur de la microstructure, de sa morphologie et de ses modes de formation. J'ai ainsi pu décrire en 2D l'évolution de la microstructure chez un grand groupe de mammifères fossiles et actuels, les cétartiodactyles, qui ont révélé que tous les caractères de l'émail ne se valent pas, et font état de différentes contraintes développementales les rendant plus ou moins labiles aux changements évolutifs. J'ai également travaillé au niveau cellulaire et en 3D avec des modèles actuels, en particulier des rongeurs, sur les rapports entre les prismes d'émail et leurs cellules sécrétrices, les améloblastes, révélant que l'agencement de ces derniers contribue en grande part à la morphologie de la microstructure. Enfin, j'ai réalisé une démarche de synthèse, en proposant un modèle de la microstructure de l'émail chez les mammifères sur la base de mes données 2D+3D. Il en est ressorti d'une part un nouveau logiciel de reconstruction virtuelle de la microstructure, Simulémail, et il a été mis en évidence différents moyens de générer la décussation chez les mammifères, ainsi que les probables mécanismes développementaux sous-jacents
I approached enamel microstructure's morphology and modes of formation with a dual angle, combining paleontological and cellular biology observations, in 2D and 3D. Studying microstructure of extinct and extant Cetartiodactyla in a phylogenetic context, I discovered that some enamel characters are more likely to evolve and change than others, which is linked to different developmental constrains. I also explored microstructure through the relationship between enamel prisms and ameloblasts, the enamel-secreting cells, showing that the arrangement of the cells is directly associated with the prisms'. Then, combining these data, I constructed a model of mammalian enamel microstructure based on 2D and 3D observations and suggested underlying cellular mechanisms, and created a new software dedicated to enamel reconstruction, Simulémail, based on this model. It helped to show that microstructure is not always created the same way for different mammals, and allowed to explore enamel characters efficiently

Abstract:
AbstractThe ‘BigBrain’ is a high-resolution data set of the human brain that enables three-dimensional (3D) analyses with a 20 µm spatial resolution at nearly cellular level. We use this data set to explore pre-α (cell) islands of layer 2 in the entorhinal cortex (EC), which are early affected in Alzheimer’s disease and have therefore been the focus of research for many years. They appear mostly in a round and elongated shape as shown in microscopic studies. Some studies suggested that islands may be interconnected based on analyses of their shape and size in two-dimensional (2D) space. Here, we characterized morphological features (shape, size, and distribution) of pre-α islands in the ‘BigBrain’, based on 3D-reconstructions of gapless series of cell-body-stained sections. The EC was annotated manually, and a machine-learning tool was trained to identify and segment islands with subsequent visualization using high-performance computing (HPC). Islands were visualized as 3D surfaces and their geometry was analyzed. Their morphology was complex: they appeared to be composed of interconnected islands of different types found in 2D histological sections of EC, with various shapes in 3D. Differences in the rostral-to-caudal part of EC were identified by specific distribution and size of islands, with implications for connectivity and function of the EC. 3D compactness analysis found more round and complex islands than elongated ones. The present study represents a use case for studying large microscopic data sets. It provides reference data for studies, e.g. investigating neurodegenerative diseases, where specific alterations in layer 2 were previously reported.

Abstract:
Due to more and more studies were made on fuel and clad failure mode in international nuclear industry, some acceptance criteria of rod ejection accident should be revised in order to consider the fuel and cladding behavior change caused by radiation. Furthermore, along with the rapid development of computer hardware and improvement in physics analysis methodology, it is necessary and it is capable to use three-dimensional method to perform rod ejection accident analysis in order to relax some conservatism. In this paper, 3D method has been applied to AP1000 equilibrium core load pattern to perform fuel temperature and fuel enthalpy analysis.

Full text
Abstract:
Abstract Interdependence between pipe-soil interaction springs in a pipe stress analysis should be considered. This example focused on a single pipe configuration “wished” in place in a clay soil. A conventional pipe stress analyses often idealizes the pipe soil interaction with a beam-spring finite element model where independence is assumed between reactions in axial, lateral and vertical directions. There is however interdependence between these springs as recognized in recent Pipeline Research Council International (PRCI) guidelines. For a frictional interface, axial resistance can be much higher than indicated by PRCI guidelines when accounting for increased lateral and vertical bearing pressure. At the same time, lateral and vertical capacities are shown to be reduced in comparison to pure vertical and lateral loading directions. This paper highlights the development of a 3D soil-spring interaction model based on a continuum finite element analysis approach. By developing a soil capacity envelope based on 3D continuum modeling, updated soil springs can reflect modified capacities depending on the direction of pipe movement. For the landslide scenarios considered in application of the model, the directional dependency is shown to change the accumulated plastic strain profile in the pipe.

Abstract:
Skeletal repair and regeneration involve a dynamic interplay of biological processes that result in spatially and temporally varying patterns of tissue formation and remodeling. For example, during bone fracture healing the cartilaginous callus that is formed initially in the fracture site is subsequently mineralized and remodeled to restore the original form and function to the injured bone. During much of this healing process, the fracture callus is comprised of a heterogeneous mixture of cartilage, fibrocartilage, multipotent mesenchymal tissue, and bone. Adding to this complexity, mechanical stimuli are known to influence the rate and type of tissues formed during skeletal healing [1]. Given the growing body of evidence that controlled mechanical stimulation may be used to enhance healing, it is of substantial interest to elucidate relationships between the distributions of local stresses and strains that develop within the healing region and the distribution of tissue types that form. While histomorphometry is a well established approach for characterizing the latter, it has historically been limited to analyses of a small number of two-dimensional sections of tissue. Such 2D sampling may be inadequate for quantitative characterization of the irregular geometry and heterogeneous composition of healing tissues. In this study, we report on a 3D histomorphometric method and apply this method to an in vivo model of skeletal repair [2] in which a bending stimulus delivered to a healing bone defect results in the formation of predominantly cartilage tissue, rather than bone.
