Finite element simulation of additive manufacturing with enhanced accuracy
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized by multiple ...
Model order reduction methods for sensor data assimilation to support the monitoring of embankment dams
The latest monitoring and asset management technologies for large infrastructures involve digital representations that integrate information and physical models, exist in parallel to the real-life structures, and are ...
Anàlisi de susceptibilitat torrencial en conques d’alta muntanya a partir de la proposta de paràmetres indicadors : construcció d'una base de dades multidisciplinària per al desenvolupament d'una zonificació de perillositat torrencial : cas específic d’Andorra
Over the last 40 years, in Europe in general and in many mountainous regions in particular, there have been major instances of severe flood episodes (more than 100) which have resulted in more than 700 deaths and billions ...
Evaluación de proyectos de infraestructuras de transporte en dos etapas con impactos de no directa monetización
The constant and rapid population growth goes hand in hand with an increased demand for services that governments have the duty to satisfy with the problem of limited financial resources. Transport infrastructure is one ...
Identification of material properties and phase distribution of heterogeneous materials through data-driven computational methods : towards an enhanced constitutive space
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing models can lead ...
Static and dynamic global stiffness analysis for automotive pre-design
In order to be worldwide competitive, the automotive industry is constantly challenged to produce higher quality vehicles in the shortest time possible and with the minimum costs of production. Most of the problems with ...
Development of a machine learning based methodology for bridge health monitoring
In recent years the scientific community has been developing new techniques in structural health monitoring (SHM) to identify the damages in civil structures specially in bridges. The bridge health monitoring (BHM) systems ...
Modelling thermo-mechanical response of metal canister disposed in engineered barrier systems
The main objective of this thesis is to describe and implement a rate-dependent (viscoplastic) constitutive equations for copper based canister using a single internal state variable and use it for modelling disposal schemes ...
Direct numerical simulation of multi-phase flow in complex media
In numerous applications, two-phase liquid-gas transport at sub-millimeter length scales plays a substantial role in the determination of the behavior of the system at hand. As its main application, the present work focuses ...
Assessing the socio-economic impacts of flash floods for early warning at regional, national, and continental scales
Flash floods are one of the most devastating natural hazards, claiming numerous lives and tremendous economic losses. One of the main reasons for their catastrophic potential is the limited time available for precautionary ...
Geologically constrained joint inversion of hydraulic, tracer and ERT data for process visualization
Seawater intrusion (SWI) consists in the movement of seawater (SW) into freshwater (FW) aquifers, contaminating drinking water resources. SWI, along with the parallel reduction of Submarine Groundwater Discharge may lead ...
Towards stochastic methods in CFD for engineering applications
Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency of state of the art ...
Software development for the optimization of the influence of wind flows within energy applications and sustainable town planning
This thesis aims to propose and validate an innovative, fully open-source framework capable of performing multiscale analysis for the assessment of local wind flows within the urban fabric. Each part of the framework is ...
Quantifying uncertainty in complex automotive crashworthiness computational models : development of methodologies and implementation in VPS/Pamcrash
The automotive industry is constantly involved in the development of new methodologies and projects with the aim of reducing costs. During the vehicle design process, one of the most significant cost arises from building ...
Finite element methods for advection-diffusion-absorption and fluid flow problems
The objective of the thesis is to develop a numerical tool to describe how the concentration of one or more substances distributed in a fluid environment changes under the effect of three transport processes: advection, ...
Essays on second-best pricing schemes for transport infrastructure
Pricing has been advocated for a long time as a suitable policy instrument to deal with transport externalities. Recent technological developments enable the implementation of more sophisticated pricing schemes at affordable ...
Evaluación del impacto del Cambio Climático (escenarios B1 y A2) en las aportaciones futuras generadas para el horizonte de proyección 2000-2050 en las cuencas del Fluvià y la Tordera en Catalunya
The results presented in this doctoral thesis aims to evaluate the possible Climate Change effects on the water resources yield by the Fluvià river basin and the Tordera river basin, both located in the autonomous region ...
Computational modeling and rational design of flexoelectric metamaterials and devices
Piezoelectricity, the two-way coupling between electric polarization and strain is the basic mechanism behind most electromechanical transduction technologies. It is possible only in a limited number of materials, namely ...
On the mechanics of strain localization in plasticity : isotropic and orthotropic, cohesive and frictional, associated and non-associated models
In this thesis, two main topics have been covered: the mechanics of strain localization in plasticity and the performance of several mixed finite elements subjected to plastic strain localization. Throughout the thesis, ...
Towards the virtual wind tunnel for civil engineering applications
This thesis develops a numerical tool (the Virtual Wind Tunnel, VWT) for the resolution of problems involving fluid flow around structures. Due to the limitations that traditional methods may have in this context, the VWT ...
