Full textEsta tesis doctoral versa sobre el diseño, estudio e implementación de un método híbrido, sin contacto, de ensayos no destructivos (NDT, non-destructive testing) para el análisis de objetos metálicos que contienen defectos o fracturas internas. Proponemos una técnica híbrida opto-acústica que combina ultrasonidos generados por impacto láser como excitador y transductores de ultrasonidos como receptores. El trabajo plantea un estudio detallado de la detección y reconstrucción en 1D, 2D y 3D de defectos presentes en un objeto metálico, usando la técnica híbrida de NDT sin contacto y controlado remotamente. Nuestro dispositivo presenta varias ventajas de las técnicas fotónicas y de ultrasonidos, reduciendo al mismo tiempo algunos inconvenientes de dichos métodos tomados por separado. Nuestro método combina resultados experimentales con simulaciones numéricas basadas en el procesado de señal de alta resolución. El montaje experimental consiste en un láser pulsado de ns a una longitud de onda de 532 nm, que impacta sobre la superficie del objeto. El pulso láser se absorbe, creando una expansión termoelástica localizada que induce un pulso de ultrasonidos de banda ancha que se propaga en el material. El láser, controlado remotamente, realiza un barrido sobre un área seleccionada de la superficie del objeto. Por cada punto de excitación, el ultrasonido se propaga a través del objeto y se refleja o dispersa en los defectos del material. Dichas ondas se detectan mediante transductores y se registran en un sistema de adquisición de datos para su ulterior procesado. En un primer paso, mediante el análisis del tiempo de vuelo, podemos localizar y determinar el tamaño del defecto en una vista 1D. Las capacidades de detección de defectos internos en una muestra metálica se estudian también mediante transformación wavelet debido a sus características de multi-resolución en tiempo y frecuencia. Se aplica un algoritmo novedoso de agrupamiento (clustering) espacial y se usan los mapas resultantes de tiempo y frecuencia para estimar la posición del defecto. Para la visualización 2D de los defectos ampliamos el análisis de la señal utilizando la técnica de focalización por apertura sintética (SAFT, synthetic aperture focusing technique). Implementamos un novedoso filtro de apodización 2D, juntamente con la técnica SAFT, y demostramos que elimina efectos no deseados, mejorando la resolución de la imagen reconstruida del defecto. El siguiente paso es un análisis y reconstrucción 3D. En este caso conseguimos una configuración experimental totalmente automatizada y sin contacto, permitiendo áreas de barrido sobre diferentes caras de un objeto. Los detalles de los defectos se registran desde diferentes ángulos, consiguiéndose una completa reconstrucción 3D. Finalmente, mostramos nuestros resultados en un tema complementario, relacionado con un caso particular de propagación de ultrasonidos en sólidos. Desde un primer momento, quisimos tener una comprensión física de la propagación y difracción de ondas de ultrasonidos en materiales sólidos. El control de los patrones de difracción en sólidos, mediante el uso de lentes ultrasónicas, ayudaría a la focalización/colimación del ultrasonido, reduciendo ecos y reflexiones en la superficie de contorno, mejorando del proceso de análisis NDT. Los cristales fonónicos se usan para regular la difracción y la respuesta en frecuencia de ondas de ultrasonido que se propagan en fluidos. No obstante, dichas estructuras se han estudiado mucho menos en materiales sólidos. Hemos realizado detalladas simulaciones numéricas de la propagación de ultrasonidos en un cristal fonónico sólido y hemos demostrado efectos de focalización y autocolimación. Finalmente hemos acoplado nuestra lente de cristal fonónico al sólido objeto de estudio, demostrando que el control de la difracción se conserva en el interior de dicho objeto a través del material de acoplamiento. Finalmente, proporcionamos una conclusión general sobre el trabajo declarado en esta tesis y un plan de trabajo futuro donde esta investigación puede extenderse y expandirse aún más a aplicaciones industriales en colaboración con el mercado de producción

Full textThe budgets assigned to the repair of structures and built heritage have reached an alarming level. A scientific approach is needed to reduce these budgets by implementing tools for a more reliable and optimal assessment of existing structures. Non-destructive testing (NDT) techniques constitute one of approaches adapted to real conditions. These techniques are based on well-known physical principles. Many companies offer their services in NDT domain today but many challenges remain. The two particular needs of structure managers are the optimization of the assessment strategy (where to measure? how many testing points? what technique(s) and what precision?) and the quantification of mechanical properties of materials or durability indicators such as the compressive strength, the carbonation depth, the moisture content. The questions are how to estimate these properties from measurements performed, and what are the accuracy and reliability of the evaluation?This thesis is part of two French research projects: ACDC-C2D2 and ANR EVaDéOS. The main objective is to analyze the variability of non-destructive testing (NDT) measurements for assessing the spatial variability of concrete in real conditions. NDT techniques considered are chosen as being complementary: radar, electrical resistivity, ultrasonic, rebound hammer. The results are obtained from a wide campaign of measurements, which was performed on concrete slabs of a testing site and on two existing structures. The analysis of the NDT variability makes it possible to assess the necessary minimum number of measurements for a desired level of confidence. Furthermore, the spatial correlation of the data was modeled using the variogram analysis. In some cases, the results show that NDT measurements are not spatially independent. The correlation lengths identified depend on the measured property and the concrete of the structure inspected. They are a new result, which will provide on one hand a better evaluation of spatial variability of concrete and on the other hand a more realistic input of reliability calculations of structures. The correlation length allows also the identification of an optimal sampling distance on existing structure within the monitoring time or the implementation of additional analyses (eg. core, complementary or more reliable NDT) and a better representation of the spatial mapping of concrete properties.Within the framework of the ANR EvaDéOS research project, the effects of carbonation and of moisture gradients on NDT measurements were studied. This work aims to study the sensitivity of NDT techniques for assessing these two durability indicators and their impact on the variability of NDT measurements. In laboratory, the experimental surveys were carried out on testing specimens having different depths of carbonation or moisture gradients. The effect of carbonation was quantified for several parameters: electrical resistivity, ultrasonic pulse velocity and rebound hammer. With respect to the variability of NDT measurements, the effect of carbonation is only significant in the case of saturated concrete, in particular for the local variability of electrical resistivity and rebound hammer. This effect is weak in comparison with the effect of saturation degree. The first results show also that the measurements of electrical resistivity would follow moisture gradients in concrete

Full textInfrared thermography is a widely used method for characterization of thermophysical properties of materials. The advent of the laser diodes, which are handy, inexpensive, with a broad spectrum of characteristics, extend metrological possibilities of infrared cameras and provide a combination of new powerful tools for thermal characterization and non destructive evaluation. However, this new dynamic has also brought numerous difficulties that must be overcome, such as high volume noisy data processing and low sensitivity to estimated parameters of such data. This requires revisiting the existing methods of signal processing, adopting new sophisticated mathematical tools for data compression and processing of relevant information.New strategies consist in using orthogonal transforms of the signal as a prior data compression tools, which allow noise reduction and control over it. Correlation analysis, based on the local cerrelation study between partial derivatives of the experimental signal, completes these new strategies. A theoretical analogy in Fourier space has been performed in order to better understand the «physical» meaning of modal approaches.The response to the instantaneous point source of heat, has been revisited both numerically and experimentally. By using separable temperature fields, a new inversion technique based on a double singular value decomposition of experimental signal has been introduced. In comparison with previous methods, it takes into account two or three-dimensional heat diffusion and therefore offers a better exploitation of the spatial content of infrared images. Numerical and experimental examples have allowed us to validate in the first approach our new estimation method of longitudinal thermal diffusivities. Non destructive testing applications based on the new technique have also been introduced.An old issue, which consists in determining the initial temperature field from noisy data, has been approached in a new light. The necessity to know the thermal diffusivities of an orthotropic medium and the need to take into account often three-dimensional heat transfer, are complicated issues. The implementation of the double singular value decomposition allowed us to achieve interesting results according to its ease of use. Indeed, modal approaches are statistical methods based on high volume data processing, supposedly robust as to the measurement noise

Full textO trabalho apresentado nesta tese foi desenvolvido no Departamento de Engenharia Civil da Universidade do Minho e no Departamento de Engenharia Estrutural do Politécnico de Milão, Itália. A prática moderna na conservação de edifícios históricos é uma tarefa complexa que requer um diagnóstico profundo e cuidadoso. A investigação preliminar é essencial afim de intervir correctamente e com sucesso. Os objectivos dessa investigação são recolher de informação apropriada sobre o edifício ou a estrutura, e avaliar as propriedades mecânicas dos materiais, sendo esta última uma tarefa difícil devido à complexidade de materiais e alvenarias antigos. É imprescindível conhecer o estado de conservação da estrutura, a extensão dos danos, a ocorrência de humidades, a geometria e características escondidas tais como vazios, fendas e destacamentos. Com o intuito de aumentar o conhecimento sobre materiais de construção antigos, foi efectuada a caracterização de tijolos cerâmicos provenientes de seis mosteiros Portugueses do século XII a XIX. Os resultados mostraram uma grande dispersão, evidenciando as seguintes características: porosidade e sucção elevadas e resistência à compressão baixa. A composição química indica que estes tijolos não foram fabricados com o mesmo tipo de matéria-prima que os artefactos antigos de cerâmica. As restrições à remoção de material para efeitos de amostragem ou para a realização de testes destrutivos são muito elevadas. Assim, nas últimas décadas, o uso de técnicas não destrutivas para investigação e diagnóstico de edifícios históricos aumentou de maneira significativa. No entanto, a avaliação da resistência à compressão e doutras propriedades mecânicas dos materiais antigos utilizando técnicas não destrutivas permanece um desafio. Uma metodologia semi-destrutiva recente baseada na microperfuração é apresentada neste trabalho para a caracterização de tijolos cerâmicos dos séculos XII a XIX. Os resultados mostram que é possível estimar de maneira fiável a resistência à compressão dos tijolos através de curvas de regressão usando a técnica de microperfuração adoptada neste trabalho. A substituição de materiais de construção antigos é um tema relevante para o património arquitectónico. Os materiais modernos são geralmente incompatíveis, exibindo uma resistência e um módulo de elasticidade muito mais elevados. Assim, este trabalho também inclui o estudo de tijolos fabrico tradicional, e que se destinam à substituição de tijolos antigos. Este estudo mostra que os tijolos modernos são mais duráveis mas evidenciam uma resistência à compressão semelhante. Além disso, as correlações propostas anteriormente para a resistência à compressão permanecem válidas para os tijolos modernos de fabrico tradicional. Estava prevista a construção de réplicas de paredes de alvenaria antigas com recurso aos tijolos modernos de fabrico tradicional e argamassa de cal de baixa resistência, com vazios e outras inclusões colocados no seu interior. Essas paredes seriam testadas utilizando outra técnica não destrutiva, que não se encontra facilmente disponível em Portugal. O Radar de Prospecção Geotécnica é uma técnica de investigação não destrutiva que permite detectar alterações de materiais através das suas propriedades dieléctricas. O Radar de Prospecção Geotécnica foi empregue na determinação da geometria e na detecção de características escondidas em elementos de alvenaria tais como vazios, fendas e destacamentos. A determinação dessas características é essencial devido ao elevado grau de heterogeneidade das estruturas antigas e às implicações destas no desempenho estrutural dos edifícios. Assim, através duma série de exemplos em provetes laboratoriais e in situ, o Radar de Prospecção Geotécnica foi usado para ajudar na detecção de características geométricas e para encontrar elementos metálicos e vazios em alvenaria histórica. Os ensaios em provetes laboratoriais incluem duas paredes de três panos em alvenaria de pedra para avalização geométrica dos panos exteriores, detecção de vazios e elementos de madeira, e uma terceira parede de alvenaria mais complexa, construída com um número significativo de deficiências, diferentes materiais (tijolo e pedra) e elementos com diferente geometria, simulando situações comuns em edifícios históricos. Os ensaios in situ, foram efectuados em diversos monumentos antigos localizados em vários países Europeus para avaliar o desempenho da técnica numa série de aplicações distintas. A medição no modo de reflexão (2D) com o Radar de Prospecção Geotécnica foi efectuada em todos os casos e produziu resultados satisfatórios relativamente à avaliação das características geométricas dos painéis de alvenaria assim como na localização de outras características (vazios, fendas, destacamentos) e objectos (elementos em madeira e metálicos) que se encontram frequentemente em elementos estruturais alvenaria. Técnicas de aquisição mais precisas e rotinas de processamento de sinais mais avançadas foram utilizadas quando é necessário um posicionamento mais preciso e para a avaliação das dimensões de prováveis objectos. Aquisições para a obtenção de volumes 3D foram efectuadas, permitindo obter o posicionamento tridimensional de vazios cilíndricos, de barras de aço e dum balaústre de betão. No entanto, esta técnica não reproduziu com suficiente precisão as dimensões dos objectos devido, essencialmente, à resolução da antena quando comparado com as dimensões do respectivo objecto. Para detectar camadas de pequena espessura na alvenaria, de difícil detecção através de perfis 2D em reflexão, foram efectuadas medições em modo de transmissão. A partir dos resultados dos tomogramas foi possível distinguir o material deteriorado do material são. Devido à grande quantidade de dados necessária, ao tempo dispendido durante a aquisição no local e aos recursos informáticos elevados para aplicar os algoritmos de reconstrução 3D e tomografia, essas técnicas apenas podem ser aplicadas localmente, caso as aquisições normais em modo de reflexão não permitam obter a informação necessária.
The work presented in this thesis has been developed at the Department of Civil Engineering of University of Minho, Portugal, and at the Department of Structural Engineering of Polytechnic of Milan, Italy. Modern practice in conservation of historical buildings is a complex task that requires a deep and careful diagnosis. Preliminary investigation is essential in order to intervene correctly and successfully. The objectives of such investigation are to gather adequate information about the building or structure, and to evaluate the mechanical properties of materials, being the latter a difficult task due to the complexity of old materials and historic fabrics. Necessary information is the state of conservation, the extent of damages, the presence of moisture, the geometry and hidden features such as voids, cracks and detachments. In order to increase the knowledge about ancient building materials, characterization of clay brick from historic monuments in Portugal was performed in bricks from the 12th to 19th century, collected from six monasteries. The results showed a large scatter, and the main characteristics are high porosity, high suction and low compressive strength. Chemical composition indicates that bricks are not prepared with the same raw materials as old clay artefacts. The restrictions to remove material for mechanical sampling or to carry out destructive tests are very large. Therefore, in the last decades, the use of non-destructive testing techniques for investigation and diagnosis of historical buildings has increased significantly. However, the evaluation of the compressive strength and other mechanical properties of historic materials using such techniques remains a challenge. A recent minor-destructive methodology based on microdrilling is used in this research work for the characterization of clay bricks from the 12th to 19th century. The results show that it is possible to reliably estimate the compressive strength of bricks by means of regression curves using the adopted microdrilling technique. The replacement of old material is a matter of concern in every intervention in architectural heritage. Modern materials are usually incompatible, as they present much higher strength and elastic modulus. Thus, this work addresses also the study of traditional handmade clay bricks as replacing bricks. The study shows that new bricks are more durable but exhibit comparable compressive strength. Moreover, the proposed correlations for compressive strength of ancient bricks remain valid for new traditional handmade clay bricks. Originally, it was planned to use new handmade bricks and weak lime mortars to build replicas of ancient masonry walls, with voids and other inclusions. These would be tested using another technique, which is fully non-destructive and not easily available in Portugal. Ground Penetrating Radar is a non-destructive technique that allows the detection of material changes through changes in dielectric properties. Ground Penetrating Radar was used to determine the geometry and to map hidden features of masonry such as voids, cracks and detachments. The detection of these properties is of high relevance due to the high heterogeneity of old structures, which has implications in the structural performance of buildings. Thus, through a series of examples in laboratory specimens and in situ, the Ground Penetrating Radar was used to help in the detection of geometrical characteristics and to find metallic elements and voids in masonry. The tests in laboratory specimens included two three-leaf stone masonry walls for the geometrical assessment of the exterior panels, the detection of voids and embedded wood beams, and a third complex stone/masonry wall built with a significant amount of deficiencies, construction materials and elements with different geometry, simulating typical situations on historical buildings. The experiments in situ were performed in several masonry monuments from different European countries to assess the performance of the technique for a number of applications. Radar measurements in reflection mode (2D) were carried out in every case and produced satisfactory results regarding geometry assessment of masonry leaves and in the location of features (air voids, cracks, detachments) and objects (wood beams, steel objects) that are often found in masonry structural elements. More precise acquisition techniques and advanced signal processing routines were used when more accurate positioning was needed and for the assessment of the dimensions of possible objects. Acquisitions for the construction of advanced 3D volumes were performed and allowed to obtain the three-dimensional position of cylindrical voids, steel bars and concrete baluster. However, the technique failed to reproduce adequately the dimensions of the objects due, essentially, to the resolution of the antenna when compared to the dimensions of the targets. Transmission measurements were performed to detect thin layers of masonry. The resultant tomograms identify damaged and undamaged material. Due to the significant amount of data that is necessary, the time for accurate field acquisition and the large computer resources to run 3D reconstruction and inversion algorithms, these techniques can only be applied locally, if typical 2D radargrams do fail to provide the necessary information.
