This PhD thesis proposes a p-adaptive technique for the Hybridizable Discontinuous Galerkin method (HDG). The HDG method is a novel discontinuous Galerkin method (DG) with interesting characteristics. While retaining all ...
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 ...
(English) This thesis deals with finite element methods to solve compressible flow problems, an important branch of Computational Fluid Dynamics (CFD) whose applications are widespread in many areas of engineering and ...
(English) The advancements in material science and innovative manufacturing techniques have created substantial possibilities for improving the functionality of medical devices, tailoring them to specific needs. However, ...
El flujo desbordado en secciones de ríos con llanuras de inundación (secciones compuestas) presenta fuertes fenómenos tridimensionales que lo diferencian del flujo confinado en el cauce principal (asimilable a secciones ...
El crecimiento continuo de las ciudades, o la ocurrencia de un evento extraordinario de lluvia, en muchas ocasiones sobrepasa las medidas de diseño de algunos de los elementos del drenaje urbano (principalmente elementos ...
The general description of a fluid flow involves the solution of the compressible Navier-Stokes equations, a very complex problem whose mathematical structure is not well understood. It is widely accepted that these equations ...
One alternative to overcome the main drawbacks of plain concrete in tension (its brittleness and weakness) is Steel Fiber Reinforced Concrete (SFRC), a technique introduced in the 70's, which consists of adding steel fibers ...
Based on the laboratory, field and numerical results, the post-rupture strength defined firstly by Burland (1990) is verified and introduced in this thesis to describe the two-stage post-peak strain-softening characteristics ...
The unique electro-mechanical coupling properties of ferroelectrics make them ideal materials for use in micro-devices as sensors, actuators and transducers. Nevertheless, because of the intrinsic brittleness of ferroelectrics, ...
(English) This doctoral thesis addresses one of the most significant challenges facing the Spanish administration: the efficient selection and management of public investments. To achieve this goal, the 'Public Investment ...
In order to be worldwide competitive, the automotive industry is constantly challenged to produce higher quality vehicles in the shortest time possible and with the minimum costs of production. Most of the problems with ...
This paper presents a numerical approach for the simulation of reinforced concrete pieces in three dimensions, using embedded discontinuity elements, based on the strong discontinuity approach. In turn, this work is divided ...
(English) This thesis covers the development of large-scale numerical methods for the simulations of partial differential equations on arbitrarily complex geometries. The target application of this thesis is the structural ...
