Determinación simplificada del módulo de deformación del hormigón de presas
(2002)
Conference report
Open AccessLa determininación del módulo de elasticidad del hormigón de presas es difiícil tanto en medidas directas en la presa como mediante probetas, ya que se requieren ensayos con probetas de gran dimensión y, consecuentemente, ... -
Evaluación de la sostenibilidad de estructuras de contención de tierras: sensibilidad en las funciones de valor y en la ponderación de escenarios de toma de decisión
(Sociedad Española de Mecánica del Suelo e Ingeniería Geotécnica, 2022)
Conference lecture
Restricted access - publisher's policyLos muros de contención son estructuras geotécnicas con una amplia gama de soluciones para realizar la misma función. Cada vez más, se les pide a los ingenieros geotécnicos que encuentren la mejor solución entre varias ... -
Numerical modelling of two-phase flow in fractured rock masses using zero-thickness interface elements
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIn recent years, the authors and co-workers have developed a 3D finite element model for coupled thermo-hydro-mechanical (THM) problems in fractured rock masses. Zero-thickness interface elements are used for taking into ... -
Iterative strategies based on constitutive dissipation
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessFE formulation of solid mechanics problems typically require iterative strategies to solve the resulting nonlinear system. Basic strategies with prescribed load values, such as the Newton-Raphson method, are not valid in ... -
New results in 3D-mesomechanical coupled analysis of external sulphate attack in concrete
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessExternal Sulphate Attack (ESA) is one of the main degradation processes affecting concrete structures. It takes place when the concrete is in an environment rich in sulphate ions and with a high humidity index. Once it has ... -
Effect of long-term pore pressure evolution on the integrity of cement plugs of abandoned oil wells in CCS sites
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIn the context of Carbon Capture Storage (CCS) in abandoned hydrocarbon reservoirs, a preliminary study of the effects of pore pressure evolution on the integrity of oil-well cement seals is performed. A 2D cross-section ... -
Transient large heat advection in fractured rock: a zero-thickness interface formulation
(International Centre for Numerical Methods in Engineering (CIMNE), 2021)
Conference report
Open AccessIn a fractured rock mass, the existence of discontinuities may generate preferential paths where the hydraulic flow velocities are frequently much higher than in the porous medium and heat advection tends to dominate over ... -
Improving urban metabolism: bi-directional energy and environmental benefits of rooftop greenhouse and building integration
(International Building Performance Simulation Association (IBPSA), 2019)
Conference report
Open AccessRapid global urbanisation in 21st century results in cities consuming vast resources but also offering unique opportunities for more integrated and circular resource management. This work investigates potential benefits ... -
Numerical modeling of crack propagation using zero-thickness interfaces elements and configurational mechanics
(International Association of Fracture Mechanics for Concrete and Concrete Structures, 2019)
Conference report
Restricted access - publisher's policyThe prediction of crack trajectories is one of the major challenges of existing numerical methods for the mechanical behavior of concrete and other quasi-brittle materials. For this purpose, this paper describes a methodology ... -
Análisis 2D y 3D de la fractura del hormigón por ataque sulfático externo
(Grupo Español de Fractura, 2019)
Conference report
Restricted access - publisher's policyEl hormigón puede degradarse debido a diferentes formas de ataques químicos. Este artículo se centra en uno de ellos, el ataque sulfático externo. Un modelo de difusión-reacción se ha combinado en un contexto acoplado a ... -
Modelling acid attack of oilwell cement exposed to carbonated brine: effect of specimen geometry on experimental results
(2019)
Conference report
Open AccessIn recent years, the authors and co-workers have developed a diffusion-reaction model for the degradation process of oilwell cements exposed to carbonated brines in the context of CO2 capture and storage in abandoned oil ... -
New developments in the application of configurational mechanics to crack propagation
(2019)
Conference report
Open AccessThe numerical description of discrete cracks and their propagation remains one of the main difficulties in the modeling of quasi-brittle materials such as rock or concrete. An emerging powerful approach is the use of ...
