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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
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 ...
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 ...
