(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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
