The main objective of this work is to study the long-term and residual flexura! strength of Near Surface Mounted (NSM) strengthened Reinforced Concrete (RC) beams with Carbon Fiber Reinforced Polymers (CFRP) strips when ...
González Ruiz, Jose Antonio (Data de defensa: 2024-05-27)
Historically, the manufacture of advanced composite parts has been characterised by low-volume production, but is increasingly moving towards mass production. This new scenario, where competitiveness is on the rise, requires ...
Marín Hernández, Lorena (Data de defensa: 2015-11-13)
In the common design and certification process, a large number of experimental tests, going from small specimens to the full structure, are performed. In these tests, the environmental conditions, especially temperature ...
Guillamet Busquets, Gerard (Data de defensa: 2016-07-11)
Departing from an emerging technology such as the spread tow thin-ply technology, in which the ply thickness can be significantly reduced, the overall purpose of this thesis is motivated by the industry need to better ...
Sasikumar, Aravind (Data de defensa: 2019-07-18)
Despite the weight savings, composite materials are vulnerable to impact loads mainly due to the alarming reduction in the compression after impact strength (CAI). This thesis exploits the potential of laminate designs ...
Bagudanch Frigolé, Isabel (Data de defensa: 2017-11-16)
Incremental Sheet Forming (ISF) technology has been mainly applied on metallic sheets during the last years. ISF is used due to its flexibility, low costs, low batch production, production of complex geometries and customized ...
López Sánchez, Ángel (Data de defensa: 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 ...
Vergés Tejero, Arnau (Data de defensa: 2021-03-12)
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 ...
