External reinforcement techniques with CFRP laminate adhered to concrete elements have advanced greatly over the past decade, obtaining a more effective method further lightweight and reliable. These advances have resulted ...
El reciclado de los pavimentos asfálticos deteriorados no es una idea nueva, no obstante, con el aumento de las exigencias medioambientales y económicas se ha convertido en una alternativa cada vez más utilizada por ...
In recent years the increase in waste generated by various sectors has caused problems of waste management that mostly have as final destination the landfills; however, this option it is unacceptable for the economic and ...
Las transformaciones que se han venido produciendo en el sistema productivo, a lo largo de los últimos cincuenta años en España, con la pérdida de peso de la actividad propiamente manufacturera en beneficio de los servicios, ...
This thesis presents an experimental approach on the subject of cracking in soils due to changes in environmental conditions, where research is mainly directed to the soil-air interface and the effect of boundary conditions. ...
The thesis focuses on the experimental and theoretical aspects of the process of cracking in drying soils. The results and conclusions were drawn from an exhaustive experimental campaign characterised by innovative ...
Fluvial bifurcations are systems that have a great influence on human society. Their formation and evolution can affect to activities as agriculture or industry and a good knowledge of the mechanisms that affect the processes ...
(English) The aim of this thesis is to improve our understanding of the behaviour of mountain rivers and to predict their morphological functioning under conditions of low relative submergence. Mountain rivers have received ...
(English) Interferometry with Synthetic Aperture Radar (InSAR) is a remote sensing technique to measure displacements of the observed surface, either the ground or any structure on it. Although the systematic acquisition ...
La tesis se enmarca en la caracterización, a nivel material, de la fractura del hormigón reforzado con fibras de acero (SFRC) bajo solicitaciones de tracción y cortante, y sobre la determinación de parámetros que representan ...
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, ...
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 ...
El flujo desbordado en secciones de ríos con llanuras de inundación (secciones compuestas) presenta fuertes fenómenos tridimensionales que lo diferencian del flujo confinado en el cauce principal (asimilable a secciones ...
(English) Cycles in the construction sector and economy disguise what appears to advance in occupational risk prevention when, unfortunately, the AECO sector maintains very high accident rates. The zero accident target is ...
En la ingeniería estructural, uno de los desafíos constantes es encontrar nuevas formas de proteger las estructuras de las fuerzas medioambientales. El aislamiento sísmico se ha mostrado como una forma efectiva de reducir ...
This dissertation presents high-order hybridisable discontinuous Galerkin (HDG) formulations coupled with implicit Runge-Kutta (RK) methods for the simulation of one-phase flow and two-phase flow problems. High-order-methods ...
La informació sobre el temps de viatge és l'indicador clau en el funcionament operatiu d’una autopista i un dels inputs més apreciats pels seus usuaris. Tot i això, no ha estat fins molt darrerament que els operadors ...
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 ...
The doctoral thesis "Innovative mathematical and numerical models for studying the deformation of shells during industrial forming processes with the Finite Element Method" aims to contribute to the development of finite ...
