En el articulo se describe un procedimiento para la determinación de coeficientes de seguridad frente al deslizamiento de cuñas de roca pertenecientes a los estribos de presas bóveda. La metodología requiere un cálculo ...

Willam´s test has been often used to compare constitutive models which take into account induced anisotropy due to damage and cracking. This numerical test emulates the continuous rotation of the principal stress and ...

This numerical study deals with the analysis of rock specimens from a micromechanical point of view. The analysis is based on the Finite Element Method (FEM) with fracture-based zero-thickness interface elements, and ...

Alkali-Silica Reaction (ASR) is a particular type of chemical reaction in concrete, which produces cracking and overall expansion of the affected structural element due to the formation of expansive reaction products within ...

In this paper, an existing mesomechanical model for cementitious materials is extended to the domain of diffusion-driven phenomena. The model is based on the Finite Element Method, and uses zerothickness interface elements ...

In recent years, the authors and co-workers have developed a diffusion-reaction model for the degradation process of oil-well cements exposed to carbonated brines in the context of CO2 capture and storage in abandoned oil ...

Moisture diffusion and related fluid pressures play a key role in cracking and spalling of concrete subject to high temperatures. This paper describes recent developments of a mode for moisture and heat transfer in porous ...

Reservoir Geomechanics is playing an increasingly important role in developing and producing hydrocarbon reserves. One of the main challenges in reservoir modeling is accurate and efficient simulation of arbitrary intersecting ...

The 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 ...
