Modeling soil-facing interface interaction with continuum element methodology
(2022-03)
Article
Open AccessSoil-facing mechanical interactions play an important role in the behaviour of earth retaining walls. Generally, numerical analysis of earth retaining structures requires the use of interface elements between dissimilar ... -
Experimental study of the effects of mechanical restraints on ASR expansions in concrete
(2021-03)
Article
Open AccessThis paper summarizes an experimental campaign devoted to the study of the effect of (internal and external) mechanical restraints on Alkali-Silica Reaction (ASR) expansions in concrete made with sodalime (SL) glass as ... -
3D zero-thickness interface model for fracture of cement-based materials with chemical degradation
(2022-03)
Article
Open AccessIn the framework of the Finite Element Method, zero-thickness interface elements have been widely used to model fracturing processes in quasi-brittle materials in a broad variety of problems. In particular, interface ... -
THM analysis of a soil drying test in an environmental chamber: the role of boundary conditions
(Elsevier, 2022-01)
Article
Open AccessThis paper presents the numerical analysis of an experimental soil drying test carried on an initially slurry soil specimen with controlled temperature and relative humidity in a laboratory environmental chamber. The imposed ... -
Experimental analysis of desiccation cracks on a clayey silt from a large-scale test in natural conditions
(2021-07)
Article
Open AccessThis paper presents an experimental investigation on the impact of environmental variables on soil cracking in natural conditions. The test was performed on a large soil specimen of initial size 3 × 3 × 0.5 m exposed to ... -
Model for alkali-silica reaction expansions in concrete using zero-thickness chemo-mechanical interface elements
(2020-12)
Article
Open AccessAlkali-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 ... -
Application of configurational mechanics to crack propagation in quasi-brittle materials
(2021-01)
Article
Open AccessThe paper describes a numerical approach to represent cracking along non-pre-established directions, in 2-D structures or domains of quasi-brittle materials such as concrete or rock. The approach is developed on the basis ... -
Displacement-based and hybrid formulations of zero-thickness mortar/interface elements for unmatched meshes, with application to fracture mechanics
(John Wiley & sons, 2021-02)
Article
Open AccessThe present article develops two formulations of zero-thickness mortar/interface finite elements for unmatched meshes, which are implemented in a unified theoretical framework. The first one is displacement-based and may ... -
Laboratory-based spectral data acquisition of roof materials
(2020)
Article
Open AccessRoof characteristics such as material type and their properties information are essential to integrating urban agriculture (UA), rainwater harvesting systems (RWHS), and energy systems on roofs. Roof materials can be ... -
Criterios y alternativas para la evaluación de la tenacidad en hormigones con fibras de acero
(2003-07)
Article
Open AccessLos Hormigones Reforzados con Fibras (HRF) constituyen una de las innovaciones más relevantes en el campo de los hormigones especiales. La presencia del refuerzo provoca una sustancial modificación de la respuesta mecánica ... -
Quantifying energy symbiosis of building-integrated agriculture in a mediterranean rooftop greenhouse
(2020-08)
Article
Open AccessA major concern for sustainable development is urban systems energy consumption. A possible way to gain additional whole system energy efficiencies is to integrate rooftop greenhouses (iRTG) on unoccupied roofs. This work ... -
Application of zero-thickness interface elements to sanding prediction analysis
(2020-07)
Article
Open AccessA computational micromechanical analysis based on zero thickness interface elements for modelling solid prediction in hydrocarbon reservoir sandstones is presented. The model is capable of modelling localization of ...
