Advances in the development of the discrete element method for excavation processes

Labra, C. A. (Carlos Andrés) (Date of defense: 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 techniques such ...

Análisis matemático del equilibrio en estructuras de membrana con bordes rígidos y cables. Pasarelas: forma y pretensado

Viglialoro, Giuseppe (Date of defense: 2007-03-14)

Las membranas son estructuras (sin rigidez a flexión) que conforman una superficie en el espacio, con espesor mínimo. Se aproximan a una superficie geométrica y trabajan sólo mediante esfuerzos de membrana (de tracción) y ...

Applications of turbulence modeling in civil engineering

Cotela Dalmau, Jordi (Date of defense: 2016-01-15)

This thesis explores the use of stabilized finite element formulations for the incompressible Navier-Stokes equations to simulate turbulent flow problems. Turbulence is a challenging problem due to its complex and dynamic ...

Elementos estabilizados de bajo orden en mecánica de sólidos

Valverde Guzmán, Quino Martín (Date of defense: 2002-12-09)

Se proponen nuevos elementos finitos para problemas en mecánica de sólidos en el marco de una formulación estabilizada novedosa en este ámbito. Esta formulación se basa en el método de las sub-escalas, y particularmente ...

Finite element modeling of delamination in advanced composite beams and plates using one- and two-dimensional finite elements based on the refined zigzag theory

Eijo, A. (Ariel) (Date of defense: 2014-09-25)

Although laminated materials have been used for decades, their employment has increased nowadays in the last years as a result of the gained confidence of the industry on these materials. This has provided the scientific ...

Modelado de multifractura discreta en materiales quasi-frágiles

Lafontaine, Nelson M. (Date of defense: 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 quasi-brittle materials, ...

Numerical modeling of metal cutting processes using the Particle Finite Element Method

Rodríguez Prieto, Juan Manuel (Date of defense: 2014-03-06)

Metal cutting or machining is a process in which a thin layer or metal, the chip, is removed by a wedge-shaped tool from a large body. Cutting is a complex physical phenomena in which friction, adiabatic shear bands, ...

Numerical simulation of multi-fluid flows with the Particle Finite Element Method

De Mier Torrecilla, Monica (Date of defense: 2010-06-29)

La presencia simultánea de múltiples fluidos con diferentes propiedades ocurre en numerosos problemas medioambientales, procesos industriales y situaciones de la vida diaria. Algunos ejemplos son la interacción fluido-combustible ...

Stabilized finite element formulations for the three-field viscoelastic fluid flow problem

Castillo del Barrio, Ernesto (Date of defense: 2016-03-15)

The Finite Element Method (FEM) is a powerful numerical tool, that permits the resolution of problems defined by partial differential equations, very often employed to deal with the numerical simulation of multiphysics ...

Unified Lagrangian formulation for fluid and solid mechanics, fluid-structure interaction and coupled thermal problems using the PFEM

Franci, Alessandro (Date of defense: 2015-05-07)

The objective of this thesis is the derivation and implementation of a unified Finite Element formulation for the solution of uid and solid mechanics, Fluid-Structure Interaction (FSI) and coupled thermal problems. The ...
