A nonlinear quadrilateral thin flat layered shell element for the modeling of reinforced concrete wall structures
(Springer Netherlands, 2019)
In this article, a simple and accurate quadrilateral thin flat layered shell element formulation for the nonlinear analysis of reinforced concrete (RC) wall systems under static and cycling loads is presented. The 4 node ...
Understanding the cyclic response of RC walls with setback discontinuities through a finite element model and a strut-and-tie model
(Springer Netherlands, 2019)
Slender RC walls are often used in Chile and commonly, due to architectural constraint, the length of walls increases (setback) between floors designated for parking space and upper floors. These types of elements are ...
Veamy: an extensible object-oriented C++ library for the virtual element method
(Springer New York LLC, 2019)
This paper summarizes the development of Veamy, an object-oriented C++ library for the virtual element method (VEM) on general polygonal meshes, whose modular design is focused on its extensibility. The linear elastostatic ...
Los proyectos de educación ambiental: un análisis de las representaciones sociales de los actores que participan en el festival de especies migratorias
(Universidad Autónoma de Occidente, 2006-07)
Este artículo es producto de una investigación realizada en Colombia sobre el Festival de Especies Migratorias (FEM), como parte de mí tesis de maestría en comunicación. En dicha investigación se analizan las representaciones ...
Modelación por elementos finitos en un modelo de aneurisma
(Biomédica, Mecatrónica y MecánicaEscuela de Ingeniería de Antioquia EIAUniversidad CES, 2014-04-20)
Considering a model with generalized geometry and mechanical properties of the arterial wall for the peripheral vasculature aneurisms, a finite element modeling (FEM) is developed for analyzing the effects of arterial blood ...
Algoritmo de integración para materiales no lineales considerando los efectos de viscoplasticidad, endurecimiento cinemático no lineal y daño
(Civil, Ambiental Geológica e IndustrialEscuela de Ingeniería de Antioquia EIA, 2014-05-07)
In the Finite Element Method (FEM) material non-linearities are considered through incremental
formulations in terms of a pseudo-time variable for the case of rate independent models and a real time variable
in the case ...
Helechos y afines del santuario de fauna y flora de iguaque, boyacá. colombia
(Universidad Nacional de Colombia, Facultad de Ciencias, Departamento de Biología, 1996)
Se reconocen 31 géneros y 62 especies de helechos y afines en tres transectos ubicados en los sectores Carrizal, Chaina y San Pedro. En los sectores Carrizal y San Pedro, los transectos ascienden por los flancos occidental ...
Unique clusters of Archaea in Salar de Huasco, an athalassohaline evaporitic basin of the Chilean Altiplano
(2010)
Analyses of clone libraries from water and sediments of different sites from Salar de Huasco, a high-altitude athalassohaline wetland in the Chilean Altiplano, revealed the presence of five unique clusters of uncultured ...
Incomplete processing of peroxidase transcripts in the lignin degrading fungus Phanerochaete chrysosporium
(2005)
Phanerochaete chrysosporium has been thoroughly studied as a microbial model for lignin degradation. The enzymes lignin peroxidase (LiP) and manganese peroxidase (MnP), both encoded by several genes, play the main role in ...
Bacterioplankton composition in tropical high elevation lakes of the Andean plateau
(Oxford University Press, 2018)
High-elevation lakes in the tropics are subject to extreme environmental fluctuations and microbes may harbor a unique genomic repertoire, but their composition and diversity are largely unknown. Here, we compared the ...
