A plastic-damage model for concrete
(1989)
Article
Restricted access - publisher's policyIn this paper a constitutive model based on an internal variable-formulation of plasticity theory for the non-linear analysis of concrete is presented. The model uses a new yield criterion which matches experimental data ... -
A computational model for progressive cracking in large dams due to the swelling of concrete
(1990-09)
Article
Open AccessThe paper presents a computational model for the analysis of large concrete gravity dams subjected to severe damage due to internal actions. It has been observed in several operating concrete dams that the combined effects ... -

Una formulación para el estudio, por el método de los elementos finitos, de la deformación de tuberías marinas durante su instalación
(1983-10)
Article
Open AccessLa ejecución de emisarios submarinos para saneamiento y la instalación de tuberías para transporte de productos petrolíferos son ejemplos de la necesidad de conocer los esfuerzos y deformaciones que se producen en el tendido ... -
FIC–FEM formulation for the multidimensional transient advection–diffusion–absorption equation
(2020-06)
Article
Restricted access - publisher's policyIn this paper we present a stabilized FIC–FEM formulation for the multidimensional transient advection–diffusion–absorption equation. The starting point is the non-local form of the governing equations for the multidimensional ... -
Comparación de las dos metodologías de análisis y diseño más recientes de ASCE 7, para el análisis de su posible empleo en edificaciones con aislamiento sísmico de base en Colombia
(Universidad del Norte, 2019)
Article
Open AccessEl aislamiento de base es una técnica de protección sismorresistente para edificaciones, con un uso exitoso y amplio a nivel mundial. En Colombia actualmente existen algunos edificios que incorporan esta técnica, los cuales ... -
An embedded Finite Element framework for the resolution of strongly coupled Fluid–Structure Interaction problems: application to volumetric and membrane-like structures
(2020-08)
Article
Restricted access - publisher's policyThis work presents a Fluid–Structure Interaction framework for the robust and efficient simulation of strongly coupled problems involving arbitrary large displacements and rotations. We focus on the application of the ... -
Fast fluid–structure interaction simulations using a displacement-based finite element model equipped with an explicit streamline integration prediction
(2017-03)
Article
Open AccessWe propose here a displacement-based updated Lagrangian fluid model developed to facilitate a monolithic coupling with a wide range of structural elements described in terms of displacements. The novelty of the model ... -
Computational modeling of the fluid flow and the flexible intimal flap in type B aortic dissection via a monolithic arbitrary Lagrangian/Eulerian fluid-structure interaction model
(John Wiley & sons, 2019-11)
Article
Restricted access - publisher's policyIn the present work, we perform numerical simulations of the fluid flow in type B aortic dissection (AD), accounting for the flexibility of the intimal flap. The interaction of the flow with the intimal flap is modeled ... -
A bonded discrete element method for modeling ship–ice interactions in broken and unbroken sea ice fields
(Springer, 2019-10)
Article
Restricted access - publisher's policyThis work investigates the failure patterns of ice cakes and floe-ice when loaded by a moving and sloping structure (ice-breaking ships and cones). In the paper, we introduce the most frequently encountered ice-infested ... -
A unified Lagrangian formulation for solid and fluid dynamics and its possibility for modelling submarine landslides and their consequences
(2019-01)
Article
Restricted access - publisher's policyConsequences of submarine landslides include both their direct impact on offshore infrastructure, such as subsea electric cables and gas/oil pipelines, and their indirect impact via the generated tsunami. The simulation ... -
Effect of the integration scheme on the rotation of non-spherical particles with the discrete element method
(Springer, 2019-10)
Article
Open AccessThe discrete element method (DEM) is an emerging tool for the calculation of the behaviour of bulk materials. One of the key features of this method is the explicit integration of the motion equations. Explicit methods are ...
