Pons Poblet, Josep Maria (Date of defense: 2014-09-16)
The present project is aimed to analyze the steel structure from an evolutionary point of view. The study¿s context has been the 20th century on the Catalan capital city in order to see how the historical, normative and ...
González González, David (Date of defense: 2014-01-29)
Today, 3.5 and 4G systems including Long Term Evolution (LTE) and LTE-Advanced (LTE-A) support packet-based services and provide mobile broadband access for bandwidth-hungry applications. In this context of fast evolution, ...
Ortega, E. (Enrique) (Date of defense: 2014-05-12)
This work deals with the development and application of the Finite Point Method (FPM) to compressible aerodynamics problems. The research focuses mainly on investigating the capabilities of the meshless technique to address ...
Valverde Guzmán, Quino Martín (Date of defense: 2002-12-09)
Se proponen nuevos elementos finitos para problemas en mecánica de sólidos en el marco de una formulación estabilizada novedosa en este ámbito. Esta formulación se basa en el método de las sub-escalas, y particularmente ...
Moreno, E. (Elvira) (Date of defense: 2014-02-26)
The objective of this thesis is to develop and evaluate a methodology for the solution of the Navier-Stokes equations for Bingham Herschel-Bulkley viscoplastic fluids using stabilized mixed velocity/pressure finite elements. ...
Pérez Guindal, Elsa (Date of defense: 2013-12-05)
The knee joint is the largest and most complex both in humans and in canines. The internal forces that govern it, are not known exactly. Canine knee injuries are recurrent, especially in the anterior cruciate ligament, a ...
Mayugo Majó, Joan Andreu (Date of defense: 2003-09-22)
La tesis propone una metodología para el análisis de la degradación a fatiga que produce la aplicación de cargas cíclicas en un composite laminado de fibras largas.<br/>En primer lugar se han estudiado los mecanismos de ...
Casariego Vales, Pedro (Date of defense: 2014-07-08)
Since a few decades ago, the cold-formed steel industry has developed a press-forming procedure to bend trapezoidal commercial steel sheeting into an arched shape. The main quality of these arches is to be self-supporting, ...
Escrig Pérez, Christian (Date of defense: 2015-10-02)
The global tendency to apply sustainability criteria in most of productive fields, as well as, the limited durability and the pathologies that suffer the reinforced concrete elements, are aspects that directly affect the ...
Ferrer Ballester, Miquel (Date of defense: 2005-11-10)
El fallo resistente de las losas mixtas se produce generalmente por el deslizamiento longitudinal entre la chapa nervada de acero y el hormigón. La dificultad de diseño de chapas para losas mixtas reside en asegurar su ...
Pérez Martínez, M. (Marco) (Date of defense: 2012-02-06)
Composite laminates offer decisive advantages compared to more traditional materials, especially in structural applications where weight is a design-limiting factor. However, they have also shown a susceptibility to impact ...
Eijo, A. (Ariel) (Date of defense: 2014-09-25)
Although laminated materials have been used for decades, their employment has increased nowadays in the last years as a result of the gained confidence of the industry on these materials. This has provided the scientific ...
Velásquez Villada, César Augusto (Date of defense: 2016-02-01)
The natural hazard risk is a contingent liability and, thus, a sovereign risk for national governments and, therefore, it is important to assess properly the potential losses in order to design suitable policies and ...
Bernal Granados, Gabriel Andrés (Date of defense: 2014-11-09)
In the assessment of seismic risk, hazard is one of its main components, given that, from a probabilistic perspective, provides the annual rates of exceedance of the intensities of strong motion in the site or region of ...
Marulanda Fraume, Mabel Cristina (Date of defense: 2013-04-25)
El riesgo sísmico y en general los desastres futuros que puede sufrir una ciudad, una región o un país significan una obligación o pasivo contingente no explícito que puede afectar, desde el punto de vista macroeconómico, ...
Lafontaine, Nelson M. (Date of defense: 2016-01-18)
The stated goal of this work is to develop a numerical explicit finite element method able to effectively address the strain localization process, discrete fracture and fragmentation process in quasi-brittle materials, ...
Paredes López, Jairo-Andrés (Date of defense: 2013-11-11)
Esta tesis surge de la necesidad de establecer un método racional y práctico para identificar, a través del cambio de las frecuencias naturales , el daño en estructuras de hormigón armado. Por lo que se desarrolla un nuevo ...
Velázquez Ameijide, Juan (Date of defense: 2015-03-23)
This dissertation deals with obtaining the mechanical properties of the cortical bone of the human ribs. One hundred one samples from 76 donors were tested for this study. The number of tested samples significantly ...
Mora, D. F. (Diego Fernando) (Date of defense: 2013-04-26)
Cementitious materials such as mortar or concrete are brittle and have an inherent weakness in resisting tensile stresses. The addition of discontinuous fibers to such matrices leads to a dramatic improvement in their ...
Otero Gruer, Fermin (Date of defense: 2016-02-09)
Most of the existing materials around us can be considered composite materials, since they are composed by several phases or components at certain spatial scale. The physical and chemical properties of composites, as occurs ...
