Abstract:

In this thesis, a new set of finite element formulations are developed for computer simulation of microstructural evolution which is controlled by solid-state diffusion and grain-boundary migration. The finite element formulations are based on the classical cubic spline interpolation and form a natural extension of the linear finite element scheme which was first developed by Pan, Cocks and Kucherenko (1997). The cubic spline elements are however much more efficient numerically than the previous linear elements and make it possible to undertake large scale computer simulations of microstructur

Abstract:

Magnesium alloys have been the focus of active research especially in automotive industry for designing light weight vehicles in order to achieve better fuel efficiency and lower greenhouse gas emissions. The control of as-cast microstructure of Mg alloys is critical because many automotive components are made of Mg alloys and used in their as-cast form. Microstructure development during any casting process is controlled by solidification phenomena. Thus it is imperative to understand the relationship between casting process parameters and microstructural features to control the quality of fin

Triaxial extension experiments on Carrara Marble demonstrate that there is a continuous transition from extension to shear fracture on the basis of mechanical behavior, macroscopic fracture orientation and fracture morphology where hybrid fractures with extension and shear fracture characteristics are formed at the intermediate stress conditions. Extension fracture surfaces display discrete, highly reflective cleavage planes and shear fracture surfaces are covered with calcite gouge and display grooves and striations that are aligned parallel to slip.

Silicon oxycarbide (SiOC) is a ceramic obtained through the heating of a polymer precursor, which undergoes partial decomposition to go from an organic polymer to an inorganic ceramic. The microstructure of SiOC is not uniform at the nanometer scale, and contains nanometer sized silicon dioxide, carbon, and silicon carbide. Porous SiOC has shown great promise in applications such as lithium ion batteries, gas separation, and thermal barriers. The microstructure, and thus the properties of the SiOC, is influenced by the initial polymer and the processing conditions. In this thesis, SiOC is fabr

Abstract:

Superplastic forming (SPF) is a near net-shape forming process which offers many advantages over conventional forming operations including low forming pressure due to low flow stress, low die cost, greater design flexibility, and the ability to shape hard metals and form complex shapes. However, low production rate due to slow forming process and limited predictive capabilities due to lack of accurate constitutive models for superplastic deformation, are the main obstacles to the widespread use of SPF. Recent advancements in finite element tools have helped in the analysis of complex superplas

Abstract:

La thèse a pour but de caractériser les propriétés mécaniques de matériaux à base de fibres de bois en relation avec les propriétés intrinsèques des fibres et leur arrangement spatial complexe. Ce type de matériau, dont les caractéristiques dépendent de sa configuration, est hétérogène à différentes échelles : à l’échelle microscopique de la fibre, à l’échelle mésoscopique du réseau des fibres et à l’échelle macroscopique du matériau. Pour observer ces hétérogénéités, différents moyens expérimentaux de caractérisation sont utilisés, notamment la microtomographie aux rayons X et la corrélation

Abstract:

The Median Tectonic Line (MTL) is a major, crustal-scale fault in Japan that separates the low-P/high-T Ryoke metamorphic belt of mainly subduction related granitoids from the high-P/low-T Sambagawa Belt of accretionary complex metasedimentary rocks. Like many large, crustal-scale faults, the MTL has a long history of movement having been active predominantly as a strike-slip fault since the mid-Cretaceous. Fault rock exposures in the core of the MTL preserve a history of deformation at a range of mid- to shallow-crustal depths. Ryoke mylonites 1-5 km north of the main contact record deeper le

Orientador: Jorge Luís Akasaki<br>Resumo: Aglomerantes ativados alcalinamente (AAA) são obtidos da combinação de um precursor solido (geralmente um aluminosilicato) e uma solução alcalina de alta concentração. As vantagens de utilizar este novo tipo de aglomerante comparado ao cimento Portland, um aglomerante convencional, são as menores emissões de CO2, menor consumo de energia e a possibilidade de utilizar matérias prima renováveis e/ou resíduos. Neste sentido, este trabalho apresenta um novo resíduo da indústria da cada de açúcar: a folha de cana de açúcar. A folha apresenta um poder calorí

Abstract:

The gold market is one of the major world markets and the Italian companies place the country as one of the major players in this sector. However, the production in these companies is mostly based on the use of artisan skills, without investing in research and studies about the production processes of these materials. In fact, often the process depends on a "craft" way of working, in which the technical and scientific knowledge are dictated more by experience than by a systematic scientific approach. The international bibliography regarding the world of machining of gold alloys is not as devel
