    Modelado de multifractura discreta en materiales quasi-frágiles 

    Lafontaine, Nelson M. (Date of defense: 2016-01-18)

    The stated goal of this work is to develop a numerical explicit finite element method able to effectively address the strain localization process, discrete fracture and fragmentation process in quasi-brittle materials, ...

    Riesgo sísmico de edificaciones en términos de pérdidas económicas mediante integración de costos de reparación de componentes 

    Yamin Lacouture, Luis Eduardo (Date of defense: 2016-01-28)

    The probabilistic seismic risk assessment in terms of economic losses for building portfolios aims at the estimation of the probability distribution functions of losses. This can be done for a specific seismic event ...

    La curva híbrida de riesgo : análisis retrospectivo y prospectivo del riesgo por fenómenos naturales 

    Velásquez Villada, César Augusto (Date of defense: 2016-02-01)

    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 policies and ...

    Numerical simulation of fatigue processes : application to steel and composite structures 

    Barbu, L. G. (Lucia Gratiela) (Date of defense: 2016-02-01)

    The present thesis aims at advancing an innovative computational methodology that simulates steel and composite material fracture under cyclic loading following a phenomenological approach, with calibration from both small ...

    Análisis beneficio costo probabilista de medidas de mitigación del riesgo por sismo 

    Mora Cuevas, Miguel Genaro (Date of defense: 2016-02-02)

    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 as well as the ...

    Numerical modelling of the growth and remodelling phenomena in biological tissues 

    Comellas Sanfeliu, Ester (Date of defense: 2016-02-05)

    Living biological tissues are complex structures that have the capacity of evolving in response to external loads and environmental stimuli. The adequate modelling of soft biological tissue behaviour is a key issue in ...

    Multiscale numerical modelling of microstructured reinforced composites 

    Otero Gruer, Fermin (Date of defense: 2016-02-09)

    Most of the existing materials around us can be considered composite materials, since they are composed by several phases or components at certain spatial scale. The physical and chemical properties of composites, as occurs ...

    Stabilized finite element formulations for the three-field viscoelastic fluid flow problem 

    Castillo del Barrio, Ernesto (Date of defense: 2016-03-15)

    The Finite Element Method (FEM) is a powerful numerical tool, that permits the resolution of problems defined by partial differential equations, very often employed to deal with the numerical simulation of multiphysics ...

    Análisis del comportamiento frente acciones cíclicas de muros de mampostería reforzados con materiales compuestos de matriz inorgánica y tejidos de fibras vegetales 

    Mercedes Cedeño, Luis Enrique (Date of defense: 2019-10-04)

    In order to pursue sustainable objectives in the construction industry, a new composite material using vegetal fabric coated with resin and embedded into mortar was developed, characterized and applied on masonry walls. ...
