López Ruiz, Luis Alberto (Fecha de defensa: 2021-12-02)
Construction and demolition waste (CDW) is a major environmental concern that requires immediate attention. The large volumes of CDW produced and its associated environmental effects have led to explore ...
Cardoso Nungaray, Víctor Eduardo (Fecha de defensa: 2018-04-27)
This thesis presents a proposal to simulate mechanics and dynamics of brittle fracture. A variational formulation is used to describe Lagrangian mechanics, by minimizing the difference between potential ...
Ruiz Carulla, Roger (Fecha de defensa: 2018-07-02)
The present thesis aims at the analysis of the fragmentation of rockfalls. The fragmentation is a complex phenomenon poorly understood with a lack of tools to reproduce it on rockfall simulators. The ...

Matas Casado, Gerard (Fecha de defensa: 2020-11-04)
The fragmentation process in rockfalls is a complex phenomenon that is not well understood and only a few rockfall simulation models consider it explicitly. Fragmentation significantly affects the ...
Dandar, Enkhbayar (Fecha de defensa: 2017-06-23)
Groundwater withdrawals are growing in most developing countries, including Mongolia, where freshwater resources are limited and unevenly distributed, and most surface waters are frozen during winter. ...
Arrayago Luquin, Itsaso (Fecha de defensa: 2016-10-17)
This thesis investigates the cross-section and member behaviour of cold-formed stainless steel RHS and SHS elements and proposes an alternative and more efficient design approach. Combined with aesthetic ...
Benedetti, Lorenzo (Fecha de defensa: 2017-05-11)
Strain localization and quasi-brittle failure in frictional-cohesive materials is still an open and challenging problem in computational mechanics. Owing to its complexity and the significant implications ...
Jiménez Ramirez, Belén (Fecha de defensa: 2021-01-13)
The seismic vulnerability of urban assets exposed to earthquake hazard represents a growing concern in the engineering field due to the potential risk of collapse for the buildings, and the associated ...
Monforte Vila, Lluís (Fecha de defensa: 2018-11-05)
This thesis develops a numerical technique in which the Particle Finite Element method is applied to simulate solid intrusion problems in Geotechnical Engineering. The thesis describes the numerical ...
