Un modelo de daño continuo para materiales-friccionales

Oller, S. (Sergio), 1955- (Date of defense: 1988-05-31)

Actualmente hay diversas corrientes investigadoras que han profundizado en el estudio del comportamiento mecánico de los materiales, dejando un apreciable cúmulo de experiencias aprovechables. No obstante, se encuentran ...

Un modelo de discontinuidades fuertes para la simulación numérica de la fractura en compresión, de piezas de hormigón armado en tres dimensiones

Díaz Ortíz, Guillermo Fernando (Date of defense: 2014-07-23)

This paper presents a numerical approach for the simulation of reinforced concrete pieces in three dimensions, using embedded discontinuity elements, based on the strong discontinuity approach. In turn, this work is divided ...

Understanding and mitigating the post-injection seismicity induced by fluid injection in enhanced geothermal systems

Boyet, Auregan (Date of defense: 2024-01-31)

(English) Induced seismicity due to hydraulic stimulation and circulation is a hurdle for the development of Enhanced Geothermal Systems (EGS). The monitored seismicity has occasionally reached magnitudes large enough to ...

Unfittted finite element methods for explicit boundary representations

Martorell Pol, Pere Antoni (Date of defense: 2024-02-21)

(English) This thesis covers the development of large-scale numerical methods for the simulations of partial differential equations on arbitrarily complex geometries. The target application of this thesis is the structural ...

Utilización de técnicas de estimación de error y generación automática de mallas en procesos de optimización estructural

Bugeda, G. (Gabriel) (Date of defense: 1990-03-31)

A pesar de que la utilización del método de los elementos finitos está muy extendida, es difícil determinar el nivel de precisión de los resultados obtenidos. Para ello es necesario utilizar alguno de los mallados estimadores ...

Wave propagation problems with aeroacoustic applications

Espinoza Román, Héctor Gabriel (Date of defense: 2015-05-08)

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 ...

Zero-thickness interface elements in petroleum geomechanics : sand production and hydraulic fracture

Garolera Vinent, Daniel (Date of defense: 2017-09-18)

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 ...
