Novel methodology for predicting delamination in 3D composite structures under multiple loading conditions and large process zones
ENG- The overall objective of this thesis is to provide a tool for predicting delamination in composite materials under different static and fatigue loading conditions in 3D structures. The methodology is intended to be a ...
Study of debonding in CFRP-strengthened beams and contribution of anchorage systems
The rehabilitation of buildings and infrastructure has gained importance in recent decades. Carbon Fiber-Reinforced Polymers (CFRP) are effective for strengthening Reinforced Concrete (RC) structures due to their mechanical ...
Development of constitutive models for the accurate simulation of advanced polymer-based composites under complex loading states
In recent decades, several meso-scale computational models have been developed for predicting the failure evolution and strength of composite materials. Nevertheless, the complex failure mechanisms of composites pose a ...
High-volume manufacturing of advanced composite parts: reducing waste and curing time while maintaining high performance
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 ...
On the generation of design allowables of composite coupons accounting for defects using a multi-fidelity approach
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 ...
Analysis of creep crack growth in adhesively bonded joints under mode I loading
Adhesive bonds could replace more traditional mechanical joints, making structures lighter and smoother. Stresses are distributed over a larger area, and dissimilar materials can be bonded, accommodating differences in ...
New approaches for the study and treatment of aggressive cancers
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 ...
Caracterización mediante métodos inversos numéricos y correlación digital de imágenes de las propiedades elásticas en el plano de materiales compuestos laminados producidos con fabricación aditiva
In recent years, additive manufacturing technologies (3D printing) have been introduced in different fields, such as locomotion and bioengineering, among others. Extrusion by Fused Deposition Modeling (FDM) or Fused ...
Methodology for the experimental characterisation of mode I delamination under different loading rates
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 ...
Effect of temperature on the flexural behavior of NSM CFRP strengthened RC beams under time-dependent loading and fatigue
There is a general trend towards rehabilitation and strengthening of existing reinforced concrete (RC) structures due to the costs associated with the replacement of the structural members and the environmental impact ...
Emissions reduction potential by coupling a thermoelectric generator to an exhaust heater in heavy duty vehicles
First part of this research is focused in validating the Exhaust Gas Heater (EGH) viability in reducing NOx emissions without negative effects in a standard exhaust gas circuit. Experimentation was held using a HDV Euro ...
Design and fabrication of three-dimensional scaffolds for breast cancer stem cell expansion and molecular characterization
Triple negative breast cancer (TNBC) accounts for 15-20% of the breast cancers and displays an aggressive profile, poor prognosis, high relapse risk and does not have a targeted therapy. In the last years, breast cancer ...
Predicción de la fatiga de disipadores de energía elastoplásticos para estructuras sismorresistentes
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 ...
Bond behaviour between CFRP and concrete for NSM systems under sustained loading
The rehabilitation of civil structures has been gaining importance during the last decades. Owing to their mechanical, corrosion resistance and lightweight properties, Carbon Fibre-Reinforced Polymers (CFRP) present an ...
L'Eixample Malagrida d'Olot: urbanisme i arquitectura a la Catalunya-ciutat-jardí
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 ...
Development of advanced methods to characterise the fracture behaviour of flexible bonded joints
Advanced joining technologies such as bonded joints play an important role to develop more efficient and durable structures. The present Thesis gives a step forward and proposes different solutions to characterise the ...
