    3D FEM meso-level analysis of sulphate attack in concrete: new results and developments using parallel HP computing 

    Biscaro, Caterina (Date of defense: 2024-06-07)

    (English) When concrete is subject to an environment characterised by a high humidity index and rich in sulphate ions, a concrete degradation process may be initiated due to External Sulphate Attack (ESA). The sulphate ...

    Coupled analysis of degradation processes in concrete specimens at the meso-level 

    Idiart, Andrés Enrique (Date of defense: 2009-07-10)

    En los últimos años, el análisis numérico de problemas acoplados, como los procesos de degradación de materiales y estructuras relacionados con los efectos medioambientales, ha cobrado especial importancia en la comunidad ...

    Estudio numérico del ataque ácido por CO2 en cementos de pozos de petróleo sellados 

    Martínez Estévez, Ariadna (Date of defense: 2020-06-29)

    In order to cope with the serious and urgent problem of global warming, it is imperative to reduce the impact of CO2 emissions in the atmosphere. One of the alternatives proposed involves the injection of the CO2 in deep ...

    Granular flow characterisation towards an enhanced bulk feeder selection 

    Torres Serra, Joel (Date of defense: 2021-02-26)

    In the packaging industry, a wide range of powders and bulk solids are handled in bagging equipment using different bulk feeding techniques. Quality of the packaging is critically affected by feeder performance, which is ...

    Numerical modeling of cracking along non-preestablished paths 

    Crusat Codina, Laura (Date of defense: 2018-11-05)

    The general objective of this thesis is the numerical representation of discrete cracks and their propagation using concepts of Configurational Mechanics, in such a way that their trajectory really corresponds to an energy ...

    Particle model for crushable aggregates which includes size, time and relative humidity effects 

    Tapias Camacho, Mauricio Alberto (Date of defense: 2016-12-21)

    This thesis presents a study of the mechanical behaviour of coarse-crushable aggregates, using the discrete element method (DEM). A novel DEM model has been developed taking into account particle breakage, the influence ...

    Transport of water, vapour, heat and solutes in concrete for storing radioactive waste 

    Chaparro Sánchez, M. Carme (Date of defense: 2016-03-04)

    Cementitious materials are used as barriers in radioactive waste storage. Hence, transport processes in this kind of material are important. The objective of this thesis is to improve the understanding of transport of water ...
