Moreira Filho, Carlos Augusto (Data de defensa: 2022-07-21)
This thesis develops numerical methods to improve the accuracy and computational efficiency of the part-scale simulation of Additive Manufacturing (AM) (or 3D printing) metal processes. AM is characterized ...
Puigferrat Pérez, Albert (Data de defensa: 2021-07-20)
The objective of the thesis is to develop a numerical tool to describe how the concentration of one or more substances distributed in a fluid environment changes under the effect of three transport ...
Costa Solé, Albert (Data de defensa: 2020-07-17)
This dissertation presents high-order hybridisable discontinuous Galerkin (HDG) formulations coupled with implicit Runge-Kutta (RK) methods for the simulation of one-phase flow and two-phase flow ...
Zorrilla Martínez, Rubén (Data de defensa: 2020-09-21)
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 ...
Kim, Sungchul (Data de defensa: 2021-07-21)
In this thesis, two main topics have been covered: the mechanics of strain localization in plasticity and the performance of several mixed finite elements subjected to plastic strain localization. Throughout ...
Tosi, Riccardo (Data de defensa: 2021-12-21)
Recent developments of high performance computing capabilities allow solving modern science problems employing sophisticated computational techniques. However, it is necessary to ensure the efficiency ...
Colomés Gené, Oriol (Data de defensa: 2016-03-31)
In this thesis we have developed a path towards large scale Finite Element simulations of turbulent incompressible flows. We have assessed the performance of residual-based variational multiscale (VMS) ...
Valdés Alonzo, Gabriel Rolando (Data de defensa: 2022-06-03)
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing ...
Mataix Ferrándiz, Vicente (Data de defensa: 2020-09-03)
The doctoral thesis "Innovative mathematical and numerical models for studying the deformation of shells during industrial forming processes with the Finite Element Method" aims to contribute to the ...
Herrero Casas, Albert (Data de defensa: 2013-06-07)
Fluvial bifurcations are systems that have a great influence on human society. Their formation and evolution can affect to activities as agriculture or industry and a good knowledge of the mechanisms ...
