Dam behaviour is difficult to predict with high accuracy. Numerical models for structural calculation solve the equations of continuum mechanics, but are subject to considerable uncertainty as to the ...
Irazábal González, Joaquín (Data de defensa: 2017-10-06)
The development of high-speed train lines has increased significantly during the last twenty-five years, leading to more demanding loads in railway infrastructures. Most of these infrastructures were ...
Kamram, Kazem (Data de defensa: 2013-06-21)
The development of efficient algorithms to understand implosion dynamics presents a number of challenges. The foremost challenge is to efficiently represent the coupled compressible fluid dynamics of ...
Larese de Tetto, Antonia (Data de defensa: 2012-07-05)
Rockfill dams are nowadays often preferred over concrete dams because of their economic advantages, their flexible design and thank to the great advance achieved in geosciences and geomechanics. ...
Labra, C. A. (Carlos Andrés) (Data de defensa: 2012-07-19)
Modelling of granular materials, soils and rocks has been a challenging topic of investigation for decades. Classical continuum mechanics has been used to idealize soils and rocks, and numerical solution ...
Cardoso Nungaray, Víctor Eduardo (Data 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 ...
Lafontaine, Nelson M. (Data de defensa: 2016-01-18)
The stated goal of this work is to develop a numerical explicit finite element method able to effectively address the strain localization process, discrete fracture and fragmentation process in ...
Pouplana, I. de (Ignasi de) (Data de defensa: 2018-01-25)
The objective of this thesis is the derivation and implementation of a robust Finite Element formulation for the solution of solid-pore fluid coupled problems in multi-fractured porous media. A coupled ...
Casas González, Guillermo (Data de defensa: 2018-10-30)
In this work we study the numerical simulation of particle-laden fluids, with a focus on Newtonian fluids and spherical, rigid particles. We are thus dealing with a multi-phase (more precisely, a ...
