Today, 3.5 and 4G systems including Long Term Evolution (LTE) and LTE-Advanced (LTE-A) support packet-based services and provide mobile broadband access for bandwidth-hungry applications. In this context of fast evolution, ...
A significant number of buildings are supported by load-bearing masonry walls. The preservation of these worldwide used structures is a sustainable alternative. However, there is little research about the structural response ...
The objective of this thesis is to develop and evaluate a methodology for the solution of the Navier-Stokes equations for Bingham Herschel-Bulkley viscoplastic fluids using stabilized mixed velocity/pressure finite elements. ...
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, ...
This thesis deals with the numerical simulation of welding processes. The analysis is focused either at global level, considering the full component to be jointed, or locally, studying more in detail the heat affected zone ...
This work deals with the development and application of the Finite Point Method (FPM) to compressible aerodynamics problems. The research focuses mainly on investigating the capabilities of the meshless technique to address ...
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 ...
Nowadays large part of the time needed to perform a numerical simulation is spent in preprocessing, especially in the geometry cleaning operations and mesh generation. Furthermore, these operations are not easy to automatize ...
Since a few decades ago, the cold-formed steel industry has developed a press-forming procedure to bend trapezoidal commercial steel sheeting into an arched shape. The main quality of these arches is to be self-supporting, ...
The present project is aimed to analyze the steel structure from an evolutionary point of view. The study¿s context has been the 20th century on the Catalan capital city in order to see how the historical, normative and ...
Although laminated materials have been used for decades, their employment has increased nowadays in the last years as a result of the gained confidence of the industry on these materials. This has provided the scientific ...
En estructures pretesades sotmeses a ambients corrosius, s'està estudiant la possibilitat de substituir els tendons d’acer per tendons que no pateixin els efectes de la corrosió. En aquest sentit, els materials compostos ...
In the assessment of seismic risk, hazard is one of its main components, given that, from a probabilistic perspective, provides the annual rates of exceedance of the intensities of strong motion in the site or region of ...
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 ...
This dissertation deals with obtaining the mechanical properties of the cortical bone of the human ribs. One hundred one samples from 76 donors were tested for this study. The number of tested samples significantly ...
The objective of this thesis is the derivation and implementation of a unified Finite Element formulation for the solution of uid and solid mechanics, Fluid-Structure Interaction (FSI) and coupled thermal problems. The ...
The numerical simulation in the field of civil engineering, while widely used in structural design, has not benefited from the full potential offered by new technologies for the analysis and design of composite materials ...
In this thesis the thermomechanical characterization of the shape memory alloy NiTiCu working as an actuator with different heat treatment (HT) temperatures has been carried out. The results from the tests carried on ...
The global tendency to apply sustainability criteria in most of productive fields, as well as, the limited durability and the pathologies that suffer the reinforced concrete elements, are aspects that directly affect the ...
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 ...
