A compressible Lagrangian framework for the simulation of underwater implosion problems

Kamram, Kazem (Date of defense: 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 internal air and ...

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 ...

Estudio constitutivo de materiales compuestos laminados sometidos a cargas cíclicas

Mayugo Majó, Joan Andreu (Date of defense: 2003-09-22)

La tesis propone una metodología para el análisis de la degradación a fatiga que produce la aplicación de cargas cíclicas en un composite laminado de fibras largas.<br/>En primer lugar se han estudiado los mecanismos de ...

Evaluación del daño por impacto en laminados de material compuesto mediante la respuesta dinámica

Pérez Martínez, M. (Marco) (Date of defense: 2012-02-06)

Composite laminates offer decisive advantages compared to more traditional materials, especially in structural applications where weight is a design-limiting factor. However, they have also shown a susceptibility to impact ...

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 ...

Particle finite element methods for modelling granular material flows

Dávalos Chargoy, César Emilio (Date of defense: 2014-06-19)

The aim of this work is to present a new procedure for modelling industrial processes that involve granular material flows, using a numerical model based on the Particle Finite Element Method (PFEM). The numerical results ...

Stabilized finite element methods for convection-diffusion-reaction, helmholtz and stokes problems

Nadukandi, Prashanth (Date of defense: 2011-05-13)

We present three new stabilized finite element (FE) based Petrov-Galerkin methods for the convection-diffusionreaction (CDR), the Helmholtz and the Stokes problems, respectively. The work embarks upon a priori analysis ...

Un nuevo método para la simulación numérica de problemas de partición de dominios

Cafiero Díaz, Mailhyn E. (Date of defense: 2014-12-18)

The aim of this work is to develop, implement and validate a technique for information transfer, in the domain decomposition methods, able to address coupled thermomechanical problems, with mixed displacement-pressure ...
