En esta tesis se aborda la resolución de problemas tridimensionales de Mecánica de la Fractura en materiales transversalmente isótropos y piezoeléctricos. Para ello se ha desarrollado e implementado una formulación mixta del Método de los Elementos de Contorno. Esta formulación consiste en el empleo de la Ecuación Integral de Contorno en Desp...

A novel simple method using static test data for damage detection, localization, and quanti cation in beams is presented in this paper. The method is based on the change of the de ections of the beam between a reference and a damaged state. For simply supported beams with a single damage, the maximum value of the change of de ections indicates...

This paper presents a flexibility based method for damage identification from static measurements in beam-type structures. The response of the beam at the Damaged State is decomposed into the response at the Reference State plus the response at an Incremental State, which represents the effect of damage. The damage is localized by detecting...

The performances of damage detection approaches are often tested by using numerical solutions of undamaged and damaged structures. However, the numerical results used for a preliminary analysis are useful as far as they can provide a good approach to real experimental results. This paper presents a collection of numerical results obtained from...

The benefits of Project Based Learning (PBL) to acquire technological knowledge as well as transversal skills by students are well known. However, the implementation of PBL requires additional efforts from teachers and students, as well as additional teaching resources when compared to traditional teaching. This paper presents a case study of a...

Wavelet analysis can be used in local damage detection due to its ability of revealing discontinuities induced by damage in the displacement field. This paper focuses on the application of wavelet analysis to detect and identify multiple damages using the static deflection of beams. The local damages are located by the wavelet maxima lines and...

This paper presents a new damage detection methodology for beams. It applies wavelet analysis to locate the damage from changes in the mode shapes (geometric based analysis). The proposed methodology requires the mode shapes of a reference undamaged state as well as those of the potentially damaged one. Once obtained, a continuous wavelet...

This paper uses the Continuous Wavelet Transform Analysis on mode shapes for damage identification. The wavelet analysis is applied to the difference in the mode shapes between a healthy and a damaged state. The paper also includes a novel methodology for estimating the level of noise of the experimental mode shapes based on a standard Signal...

En la Península Ibérica existen numerosas viviendas y elementos patrimoniales construidos con tierra cruda. Por otro lado, actualmente hay una tendencia creciente a revitalizar el empleo de este material en la arquitectura moderna debido a su valor ecológico y arquitectónico. Sin embargo, existe aún una falta de conocimiento científico acerca...

Abstract: This paper applies a methodology for damage detection in beams proposed by the authors. The methodology is based on a continuous wavelet analysis of the difference of mode shapes between a damaged state and a reference state. The wavelet transform is used to detect changes in the mode shapes induced by damage. The wavelet coefficients...

En este artículo se presenta parte del trabajo desarrollado para la recuperación de una escultura histórica ( El Giraldillo) desde un punto de vista mecánico, dentro del proyecto de restauración integral de dicha obra de arte. Esta escultura corona la torre de la Catedral de Sevilla, La Giralda, desde el año 1568, haciendo la función de veleta....

Existe en la actualidad un interés creciente por la construcción con tierra desde tres puntos de vista: la preservación del patrimonio histórico, la utilización de materiales constructivos más respetuosos con el medio ambiente y la estandarización de los procesos de diseño y puesta en obra de estos materiales en nuevas construcciones o...

En los últimos años ha existido un creciente interés en desarrollar nuevas metodologías que permitan la detección de daño en estructuras. La mayoría de estos métodos se basan en la caracterización de la respuesta dinámica de las estructuras, pero también existen metodologías basadas en su respuesta estática. Una de las ventajas de los...
