Sans Canovas, Daniel (Date of defense: 2013-06-26)
The use of composite materials in industrial applications such as aeronautical, aerospace or wind energy production has greatly increased in recent decades. Due to their inherent properties, these materials allow lighter, ...
Trias Mansilla, Daniel (Date of defense: 2005-04-18)
La present tesi proposa una metodología per a la simulació probabilística de la fallada de la matriu en materials compòsits reforçats amb fibres de carboni, basant-se en l'anàlisi de la distribució aleatòria de les fibres. ...
Miàs Oller, Cristina (Date of defense: 2012-12-03)
In this work, long-term behaviour of FRP RC beams has been investigated both analytically and experimentally to further extend the knowledge in this particular research domain. In this respect, a new methodology to determine ...
Gascons i Tarrés, Marc (Date of defense: 2011-12-02)
Virtual tools are commonly used nowadays to optimize product design and manufacturing process of fibre reinforced composite materials. The present work focuses on two areas of interest to forecast the part performance and ...
Sebaey Abdella, Tamer Ali Abdella (Date of defense: 2013-01-11)
The main objective of the thesis is to assess the damage resistance and damage tolerance of the non-conventional dispersed laminates and compare the response with the conventional ones. However, part of the effort is spent ...
Font Llagunes, Josep Maria (Date of defense: 2007-06-14)
Aquesta tesi tracta el problema del posicionament de robots mòbils quan, en el decurs del moviment, es realitzen mesures angulars relatives al robot de l'orientació de la recta entre un dels seus punts i punts de l'entorn ...
Blanch Font, Robert (Date of defense: 2012-03-01)
During the design phase, it creates and transforms ideas into products. It needs to know the manufacturing aspects for ensuring success and calculating the product cost while developing of designs. However, the choice one ...
Albertí Ibarz, Marta (Date of defense: 2010-06-10)
La selección de centros de mecanizado de alta velocidad es un proceso complejo que requiere de mucha experiencia, puesto que en él intervienen un gran número de variables, tanto tecnológicas como económicas. Existen ...
Garcia-Romeu, Maria Luisa (Date of defense: 2005-10-24)
Modelo de predicción de la geometría final de una pieza de chapa, radio y ángulo de doblado final, producida mediante un proceso de doblado al aire.
Ferrer Real, Inés (Date of defense: 2007-04-23)
En el proceso de diseño se toman decisiones que pueden afectar a la fabricabilidad del producto. Cuando el diseñador es experto, considera las limitaciones, las propiedades y el coste de fabricación en la fase de materialización ...
Catalán Artigas, Albert (Date of defense: 2012-05-09)
This document presents a methodology that (using tunable finite element models) allow validating during the development phase of the project, the behavior that equipment and mechanical systems will have once they are ...
Ruiz Fluvià, Joaquim (Date of defense: 2004-01-25)
La feina feta en aquest treball de tesis s'ha desenvolupat a partir de tres objectius vertebradors, que fonamentalment són:<br/>·El primer dels objectius d'aquest treball de tesis és presentar un recull dels factors que ...
López Sánchez, Ángel (Date of defense: 2004-07-27)
The objective of this research is to study the influence of several recycling cycles on the mechanical properties of four different materials made by the injection of polystyrene. <br/>The four materials studied have ...
Providência, António Bernardo (Date of defense: 2012-07-26)
This PHD is about design as a tool of interaction based in information systems, allowing not only to understand the relationship of design with the user, as also, based on User Centered Design, to create a methodology that ...
