The development of efficient algorithms to understand implosion dynamics presents a number of challenges. The foremost challenge is to efficiently represent the coupled compressible fluid dynamics of internal air and ...
Kouhi Esfahani, Mohammad (Date of defense: 2013-09-30)
This work covers a contribution to two most interesting research elds in aerodynamics, the fi nite element analysis of high-speed compressible flows (Part I) and aerodynamic shape optimization (Part II). The fi rst part ...
Larese de Tetto, Antonia (Date of defense: 2012-07-05)
Rockfill dams are nowadays often preferred over concrete dams because of their economic advantages, their flexible design and thank to the great advance achieved in geosciences and geomechanics. Unfortunately their behavior ...
Dadvand, Pooyan (Date of defense: 2007-07-13)
The world of computing simulation has experienced great progresses in recent years and requires more exigent multidisciplinary challenges to satisfy the new upcoming demands. Increasing the importance of solving ...
Vieira Chaves, Eduardo Walter (Date of defense: 2003-04-01)
El estudio de la mecánica computacional de fallo ha ganado creciente popularidad en los últimos años. Modelizar el comportamiento poscrítico de estructuras puede alcanzar un grado elevado de complejidad, debido a la ...
Labra, C. A. (Carlos Andrés) (Date of defense: 2012-07-19)
Modelling of granular materials, soils and rocks has been a challenging topic of investigation for decades. Classical continuum mechanics has been used to idealize soils and rocks, and numerical solution techniques such ...
Bernat Masó, Ernest (Date of defense: 2014-02-07)
A significant number of buildings are supported by load-bearing masonry walls. The preservation of these worldwide used structures is a sustainable alternative. However, there is little research about the structural response ...
Bonada Bo, Jordi (Date of defense: 2014-01-23)
Cold-formed thin-walled steel sections are frequently used in pallet rack structures. This type of cross-sections are normally used as a columns and contains perforations uniformly distributed enabling the connection between ...
Gil Espert, Lluís (Date of defense: 1997-02-14)
El contenido de la tesis que se presenta se ha organizado de la manera siguiente:<br/><br/>A lo largo del capítulo 2 se describen los aspectos generales del estado del arte del análisis de sensibilidad, centrándose en las ...
Mora Cuevas, Miguel Genaro (Date of defense: 2016-02-02)
In the situation to make decisions about which risk mitigation measures -RMM- to implement and the performance level required, arises the need for a quantitative analysis of benefits that may be obtained as well as the ...
Andreu Torras, Antoni (Date of defense: 2006-09-22)
Este trabajo tiene por objetivo desarrollar una estrategia orientada a resolver de forma computacional el equilibrio estático de las obras pétreas formadas por elementos unidimensionales empleando la analogía clásica de ...
Valcárcel Torres, Jairo Andrés (Date of defense: 2013-02-01)
Los daños por terremotos en edificios y sistemas esenciales han motivado la definición de estándares de comportamiento de estas instalaciones, buscando reducir las pérdidas económicas y la pérdida de funcionalidad. Varias ...
Chambi Chuquichambi, José Luis (Date of defense: 2012-11-30)
El continuo deterioro y/o daños causados en las estructuras de hormigón durante su vida útil, son fenómenos inevitables que conlleva el paso del tiempo y viene a ser un problema importante que ha conducido al desarrollo ...
Pelà, Luca (Date of defense: 2009-03-26)
The present work focuses on the formulation of a Continuum Damage Mechanics model for nonlinear analysis of masonry structural elements. The material is studied at the macro-level, i.e. it is modelled as a homogeneous ...
Blanco Ibáñez, Sergio (Date of defense: 2007-04-27)
Este trabajo presenta una reformulación de la metodología de discontinuidades fuertes de continuo para la simulación numérica del fallo material de estructuras.<br/>Los objetivos buscados han sido mejorar la robustez de ...
Guerrero Catells, Ángel (Date of defense: 2009-06-02)
El progresivo incremento de la altura de los Edificios de Gran Altura (EGA) ha aumentado las consecuencias reales y potenciales cuando irrumpen en ellos incendios naturales. A la vista de dichas pérdidas, el objeto principal ...
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 ...
