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 ...
Las biomembranas constituyen la estructura de separación fundamental en las celulas animales, y son importantes en el diseño de sistemas bioinspirados. Su simulación presenta desafíos, especialmente cuando ésta implica ...
(English) This thesis investigates numerical methods for the simulation of surface water flows, focusing on the interaction between the large scale and the local scale and its application to natural hazards. Several families ...
The finite element method is a valuable tool for simulating complex physical phenomena. However, any finite element based simulation has an intrinsic amount of error with respect to the exact solution of the selected ...
The impact of coastal storms is one of the costliest forms of natural disaster, as it affects a particularly valuable fringe both from the socioeconomic and ecologic perspectives. In addition, storm-induced erosion and ...
This thesis covers the development of monotonicity preserving finite element methods for hyperbolic problems. In particular, scalar convection-diffusion and Euler equations are used as model problems for the discussion in ...
En este trabajo se ha desarrollado un cálculo vectorial sobre estructuras discretas, análogo al de los modelos continuos. Para ello se ha considerado como espacio subyacente un multigrafo finito o variedad discreta y se ...
This thesis presents the results of applying a statistical hybrid approach for structural health monitoring using piezo actuating signals. Where, by combining statistical processing based on Principal Component Analysis ...
The main object of study of this thesis is the development of scalable and robust solvers based on domain decomposition (DD) methods for the linear systems arising from the finite element (FE) discretization of transient ...
Magnetohydrodynamics (MHD) is the physics branch that studies electrically conducting fluids under external magnetic fields. This thesis deals with the numerical approximation using stabilized finite element methods of two ...
(English) Topology optimization of incompressible structures, in which the loads on the structure come from the stresses exerted by a surrounding fluid, is a highly complex problem. This work presents a compilation of the ...
This thesis develops a numerical tool (the Virtual Wind Tunnel, VWT) for the resolution of problems involving fluid flow around structures. Due to the limitations that traditional methods may have in this context, the VWT ...
The present work is a compilation of the research produced in the field of wave propagation modeling. It contains in-depth analysis of stability, convergence, dispersion and dissipation of spatial, temporal and spatial-temporal ...
This thesis describes the extension of the Finite Element Method with zero-thickness interface elements (FEM+z) to 3D, large and complex problems in geomaterials, with special interest in petroleum geomechanics. This general ...
