The finite element method is a tool very often employed to deal with the numerical simulation of multiphysics problems.Many times each of these problems can be attached to a subdomain in space which ...
Modelling of granular materials, soils and rocks has been a challenging topic of investigation for decades. Classical continuum mechanics has been used to idealize soils and rocks, and numerical solution ...
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 ...
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 ...
In the situation to make decisions about which risk mitigation measures -RMM- to implement and the performance level required, arises the need for a quantitative analysis of benefits that may be obtained ...
Cell migration is a fundamental element in a variety of physiological and pathological processes. Alteration of its regulatory mechanisms leads to loss of adhesion and increased motility, critical steps ...
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 ...
The natural hazard risk is a contingent liability and, thus, a sovereign risk for national governments and, therefore, it is important to assess properly the potential losses in order to design suitable ...
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 ...
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). ...
