El valor agregado de las redes sociales : propuesta metodológica para el análisis del capital social

Description: En el presente trabajo se utiliza una variable reticular para estratificar un grupo de actores sociales, lo cual permite exhibir la posición estructural de sus integrantes en base al origen de su capital social. Se utiliza la variable constricción debido a que integra en una sola medida las dos fuen...

Evaluación de la técnica acoplada de elementos finitos y elementos discretos en problemas de fractura de rocas. Aplicación a voladuras en el frente de túneles

Description: El objetivo de la presente tesis es evaluar la eficiencia de un nuevo método numérico que acopla el conocido método de elementos finitos (MEF) con el método de elementos discretos (DEM) para la predicción de las multi-fracturas que se producen en los materiales sometidos a un estado de cargas determ...

A three dimensional FEM-DEM technique for predicting the evolution of fracture in geomaterials and concrete

Description: This paper extends to three dimensions (3D) the computational technique developed by the authors in 2D for predicting the onset and evolution of fracture in a finite element mesh in a simple manner based on combining the finite element method (FEM) and the discrete element method (DEM) approach Zara...

Pulse fracture simulation in shale rock reservoirs: DEM and FEM–DEM approaches

Description: In this paper we analyze the capabilities of two numerical techniques based on DEM and FEM–DEM approaches for the simulation of fracture in shale rock caused by a pulse of pressure. We have studied the evolution of fracture in several fracture scenarios related to the initial stress state in t...

Methodology for the analysis of post-tensioned structures using a constitutive serial-parallel rule of mixtures: large scale non-linear analysis

Description: The main purpose of this paper is to develop a reliable method based on a three-dimensional (3D) finite-element (FE) model to simulate the constitutive behaviour of reinforced concrete structures strengthened with post-tensioned or pre-stressed tendons well beyond the elastic domain. The post-tensio...
