Full textSingle Point Incremental Forming is a recent technology that is currently under development. Its applicability is diverse because it allows the attainment of functional parts in sheet metal without great costs. Due to this characteristic, areas such as biomechanics, rapid prototyping and products of customizable features make this process a target of interest. Unfortunately, the means of obtaining parts using single point incremental forming are limited. Usually, CNC machining centers are utilized but due to their cutting-type characteristics, the implementation of the Single Point Incremental Forming is limited and inefficient. Also, the market supply of dedicated machinery requires high investments, thus becoming an unattractive solution. A major obstacle to the application of this technique focuses on the superior time of forming especially when compared to conventional forming techniques. Another disadvantage of this process is the low dimensional accuracy, however, with the development of numerical studies and correction algorithms this problem tends to be minimized. This work aims to complete the project of a single point incremental forming machine that began in previous years. This project has the objective of overcoming the limitations of the current incremental forming machines, but not ignoring the economic factor. Also, this project aims to enlarge the horizons for future research and development of the process, not only improving the machine but also developing and understanding the forming mechanism and the consequent effects of improved material formability.
A estampagem incremental é um processo recente que está em desenvolvimento. A sua aplicabilidade é variada pois permite a obtenção de peças funcionais em chapa metálica sem grandes custos associados. Devido a esta característica, áreas como a biomecânica, prototipagem rápida e produtos de características personalizáveis fazem deste processo um alvo de interesse. Infelizmente, os meios de obtenção de peças usando estampagem incremental por ponto único são limitados. Normalmente faz-se uso de centros de maquinagem CNC adaptados, que devido às suas características próprias de corte por arranque de apara, tornam a aplicação da estampagem incremental limitada e ineficiente. Além disso, a oferta de mercado em maquinaria com características dedicadas ao uso de estampagem incremental requerem elevados investimentos, tornando-se assim uma solução pouco atractiva. Um dos principais obstáculos à aplicação desta técnica centra-se no tempo de conformação elevado, principalmente quando comparado com técnicas de estampagem convencionais. Outra desvantagem deste processo é a baixa precisão dimensional, que todavia com o avanço dos estudos numéricos e com o desenvolvimento de algoritmos de correcção tende a ser minimizado. Neste trabalho pretende-se concluir o projecto de uma máquina para realização de estampagem incremental por ponto único que teve início em anos anteriores. Este projecto tem por objectivo a obtenção de uma máquina que ultrapasse as limitações das máquinas actuais, mas não desconsiderando o factor económico. Além disso este projecto visa ampliar os horizontes para futuras pesquisas e desenvolvimento do processo, tanto na melhoria da máquina, mas também no desenvolvimento e na compreensão do mecanismo de deformação existente e aumento associado da formabilidade material.

Full textThis dissertation addresses the development and the testing of a simulation tool to be used to predict the behaviour of smart material/structures. Along with the development of the simulation tool, a new form of the model describing the behaviour of shape-memory alloy was developed and implemented. The proposed model was developed based on the existing cosine model, conventionally used in literature, but it uses hyperbolic tangent functions. The hyperbolic tangent function was chosen so as to allow the simulation of any range of temperatures. Experiments were performed to obtain the parameters to be used in the simulation and to validate the numerical results. Two different simulations were performed: a one dimensional FEA analysis with a two dimensional orientation (NiTi SMA wire simulation) and a three dimensional FEA analysis (NiTi SMA plate) [Msomi and Oliver, 2015]. Alongside the FEA analysis, two experiments were performed with the purpose of obtaining the material parameters to be used in FEA analysis and to compare the FEA results to the experimental results.

We live in a society where concepts of self, community and what is right and wrong are constantly changing. This makes it particularly challenging for young people to construct a sense of self and to identify and develop their most cherished personal and moral values. It also puts pressure on schools and society to help them do so. This thesis explores how new technologies can be used to create environments explicitly designed to help young people explore their inner worlds. I coined the term identity construction environments (ICE) to refer to computational tools purposefully designed with the goal of helping young people explore different aspects of the self, in particular personal and moral values. My contribution in this thesis involves three dimensions: theory, design and empirical research. At the theoretical level, I propose a framework through which people can think and learn about identity as a complex entity embracing multiple and contradictory values. At the design level, I describe an evolutionary process of building and investigating the use of three identity construction environments which are precursors to the one that is at the center of the empirical investigation described in this thesis.
(cont.) The three-dimensional multi-user environment I call Zora engages learners in the design of a graphical virtual city and its social organization. At the empirical level I present two studies of young people using Zora: a multicultural group of teenagers in an intensive summer workshop, and young patients in the Dialysis Unit at Boston Children's Hospital. Despite their diversity, both populations demonstrated a desire and need to explore issues of identity and values. The first study looks at how teens used Zora to express their sense of self, to create a participatory community to discuss ethical and moral issues, and to explore the relationship between personal identity and moral values. The second study focuses on how pediatric patients used Zora to escape the harshness of the dialysis treatment and to create a network to facilitate mutual support and new kinds of interactions with hospital staff. This thesis offers a theoretical framework and methodology for education in multicultural, moral and democratic values and for the potential role of computational environments in psychotherapeutic interventions.

The use of Building Information Modeling (BIM) tools is increasing across the Architectural, Engineering and Construction (AEC) industry. This technology is being adopted in many different countries, in a wide range of types of projects, and by professionals from different disciplines. In other words, BIM tools are being applied in many different contexts of use. Consequently, the requirements of its users are becoming heterogeneous and this heterogeneity hinders the development of BIM tools that can satisfy all possible user requirements. Instead, tools are developed to satisfy more broad, general, and generic needs of the AEC industry. The present thesis examines how BIM users are adapting the standard tools to satisfy their specific requirements. Utilizing the user innovation theory as the framework of analysis, the thesis examines whether and how BIM users are adapting the tools to respond to their requirements through user innovation. Studying eight specific BIM user innovation cases, from different contexts of use, the thesis presents and analyzes the processes underlying BIM user innovation, from the starting motivation, to the final distribution of the actual innovation. This analysis has two main objectives: first, to recognize whether there is user innovation in the case of BIM tools; and second, to understand how that innovation is developed. Finally, the thesis extracts patterns of innovation, and examines whether these user innovation cases fit the model described by the user innovation theory.

Full textMaterial testing is an important test to researchers in material science fields and other engineering related fields. This is the base for material evaluation prior to the application. This test is used in the engineering field to determine the strength of materials which is an aspect of assigning materials to different functions. The uniaxial tensile testing of material is the most common form of testing the strength of metallic material - usually to investigate whether or not the material is worthy of the intended application. Material testing is normally performed under uncontrolled conditions in most laboratories. Numerous attempts had been previously made in attempt to control the temperature conditions when performing the tensile test on special materials such as shape memory alloys (SMA) and other smart materials. Various methods had been employed to control the temperature during tensile testing, methods such as induction heating, warm liquid baths, etc. The aim of this study was to develop a temperature controlled environment for the Houndsfield tensile testing machine which is found at the Cape Peninsula University of Technology in the Mechanical Engineering Department workshop. This was achieved through designing and manufacturing of a thermally controlled chamber -better known as a furnace. This chamber was tested for the optimal combination of proportional, integral and derivative parameters which were tuned on the proportional integral derivative (PID) controller. Performing the tensile test under controlled thermal conditions will allow the analysis of SMAs and other materials behaviour at different temperatures. With the aid of the manufactured chamber, the superior features of the SMA will be able to be studied. The manufactured thermal chamber which is electrically powered is insulated with a special ceramic refractory material to prevent the heat from escaping the chamber. The PID controller was used to control the temperature and heating elements act as the heat source. The manufactured chamber could withstand the maximum temperature 350oC that it was initially designed for. However, the challenge of having the specimen to be tested fully inside the chamber was overcame by designing specimen connectors that connected the specimen to the tensile testing machine. Tensile tests were conducted on the SMA wire at room temperature and other various controlled temperatures and different behaviours were observed on the stress-strain graphs.

Full textindividual experiences and prejudices. For this purpose, an evolutionary methodology for the conceptual design of engineering products has been proposed. This methodology performs evaluation, combination and modification of the existing solutions repetitively to generate new solution alternatives. Therefore, initially a representation scheme, which is generic enough to cover all alternatives in solution domain, has been defined. Following that, the evolutionary operations have been defined and two evaluation metrics have been proposed. Finally, the computer implementation of the developed theory has been performed. The test-runs of developed software resulted in creative alternatives for the design task. Consequently, the evolutionary design methodology presents a systematic design approach for less experienced or inexperienced designers and establishes a base for experienced designers to conceive many other solution alternatives beyond their experiences.

Resumo: O processo de conformação plástica através da trefilação a frio de barras de aço tem como principal dificuldade o projeto da ferramenta. Ainda hoje, projetistas lançam mão de ábacos e tabelas colecionados ao longo do tempo através dos sucessos e insucessos experimentais. Tais informações, normalmente, ficam restritas às empresas ou aos poucos técnicos, dentro das suas bibliotecas particulares, onde, devido à dificuldade de acesso às informações práticas para projetar ferramentas e processos mais complexos, a fabricação de perfis trefilados tem perdido espaço para outros meios produtivos, por vezes, mais onerosos. Assim, este trabalho compila ábacos e tabelas presentes em projetos de ferramentas para trefilação ¿ seja através das experiências próprias, seja dos resultados herdados de outros técnicos ¿ e também, o escasso material bibliográfico sobre o assunto, organizando um banco de dados para a modelagem de um método que auxilie assertivamente as tarefas do projeto para ferramentas para trefilação a frio de barras de aço, utilizando-se de programas comerciais de computador. Cabe salientar que o sistema não é definitivo, dessa forma, o programa fonte é aberto e detalhado para que seja analisado e melhorado, sendo indicados os pontos de atenção onde devem ser inseridas ou modificadas informações, tornando o acesso amigável para aderência às particularidades do processo onde for aplicado
Abstract: The process of plastic conformation by cold drawing of steel bars has it's main difficulty in the tool design. Even today, designers have abacuses and tables built over time through the successes and failures experimental. Such collections of information, usually, are restricted to companies or few technicians within their private libraries Due to the difficulty of access to practical information to design tools and more complex processes, the manufacture of cold drawn profiles has lost ground to other, sometimes more expensive, productive means. This work compiles abacuses and tables collected in my 30 years in cold drawing tools' design - either through my own experiences, either from inherited results of the private collections of other technicians - and also, the scarce bibliography about the subject, organizing a database for modeling a method that assertively assists the project tasks for cold drawing steel bars tools, using commercial software. The system is not final, thereby the program has open source and detailed for to be analyzed and improved, being indicated the points where must be inserted - or changed - information, making friendly access to the particularities of the production process where it will be applied
