THE GARDEN CITY. This is the name under which Eixample Malagrida (the extension district) of the city of Olot is known; this is what it was called in the only plans available to us of the project that was born in the middle ...
Medina Escobar, Sergio Alonso (Data de defensa: 2022-11-25)
The rate-dependent behaviour of the interlaminar fracture toughness of fibre reinforced composites has been a matter of research during the last decades. However, the results obtained so far are not conclusive and further ...
Providência, António Bernardo (Data de defensa: 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 ...
Gironès Güell, Xavier (Data de defensa: 2013-01-21)
For the manufacture of gypsum powder applied and checked on its setting, using multiple components. One of the intrinsic components of construction gypsum is the anhydrite, completely dehydrated gypsum, working as inert ...
Guerrero Garcia, José Manuel (Data de defensa: 2020-02-07)
In this thesis, a micromechanical model for predicting the tensile failure process in hybrid and non-hybrid unidirectional composite materials under fibre tensile loading is developed. Derived from this, the influence that ...
Iglesias, Alex (Data de defensa: 2016-02-04)
Chatter is one of the major problems in today’s milling processes. Theoretical models to calculate stability lobes are used to predict and avoid chatter onset. However, current predictions are not accurate enough and ...
Maimí Vert, Pere (Data de defensa: 2007-04-27)
En el trabajo se definen modelos constitutivos que permiten reproducir el proceso de fallo de estructuras de materiales compuestos en distintas escalas bajo cargas estáticas. <br/>Se define un modelo constitutivo para ...
Polonio Alcalá, Emma (Data de defensa: 2023-05-17)
Although there are therapies for triple negative breast cancer (TNBC) and epidermal growth factor-mutated non-small cell lung cancer (EGFRm NSCLC), these two subtypes of cancer are very aggressive, and most patients develop ...
Kabeel, Abdallah Mahmoud Bayoumi (Data de defensa: 2015-04-15)
The main contribution of this work is to introduce analytical models able to create simple design charts that would allow designers to quickly determine the strength of quasi-brittle structures containing circular holes. ...
Vallmajó Martín, Oriol (Data de defensa: 2024-04-12)
Composite structures play a crucial role in lightweight applications due to their exceptional mechanical performance and low density. However, their anisotropic behavior and susceptibility to uncertainties, such as ...
Ricart Ferrer, Josep (Data de defensa: 2019-02-07)
The reason for the writing of this doctoral thesis arises from the commitment adopted by COMEXI in order to put its products in the market making his products more sustainable and environmentally friendly. Is in this ...
Simon Madrenas, Enric (Data de defensa: 2021-11-17)
Elastoplastic energy dissipators are used in earthquake-resistant design in order to dissipate a substantial part of the seismic energy acting on a building. They are elements that are not part of the load-bearing structure ...
Veciana, Joaquim M. (Joaquim Maria) (Data de defensa: 2007-11-14)
Molts sistemes mecànics existents tenen un comportament vibratori funcionalment perceptible, que es posa de manifest enfront d'excitacions transitòries. Normalment, les vibracions generades segueixen presents després del ...
Wagih Abdallah Abdel Hady, Ahmed (Data de defensa: 2018-05-28)
The objective of the thesis is to provide scaling tool predicting the response of composite structures under out-of-plane loading by testing small coupons. This global objective cannot be achieved without understanding the ...
Barris Peña, Cristina (Data de defensa: 2011-02-11)
El uso de materiales compuestos de matriz polimérica (FRP) emerge como alternativa al hormigón convencionalmente armado con acero debido a la mayor resistencia a la corrosión de dichos materiales. El presente estudio ...
Turon Travesa, Albert (Data de defensa: 2006-12-18)
Es desenvolupa una eina de disseny per l'anàlisi de la tolerància al dany en composites. L'eina pot predir el inici i la propagació de fisures interlaminars. També pot ser utilitzada per avaluar i planificar la necessitat ...
González Juan, Emilio Vicente (Data de defensa: 2011-03-08)
La aplicación de materiales compuestos de matriz polimérica reforzados mediante fibras largas (FRP, Fiber Reinforced Plastic), está en gradual crecimiento debido a las buenas propiedades específicas y a la flexibilidad en ...
Quintana i Badosa, Guillem (Data de defensa: 2010-01-14)
La millora de la productivitat i la qualitat són indubtablement dues de les principals exigències del sector productiu modern i factors clau per la competitivitat i la supervivència. Dins aquest sector,la fabricació per ...
Baena Muñoz, Marta (Data de defensa: 2011-02-14)
El uso de barras de materiales compuestos (FRP) se propone como una alternativa efectiva para las tradicionales estructuras de hormigón armadas con acero que sufren corrosión en ambientes agresivos. La aceptación de estos ...
Quintanas Corominas, Adrià (Data de defensa: 2019-10-11)
