Local Maximum Entropy Material Point Method applied to quasi-brittle fracture
(Pergamon-Elsevier Science Ltd, 2021-01)
This work aims to introduce an alternative technique to address the fracture process of brittle and quasi-brittle materials under the Material Point Method (MPM) framework. With this purpose the eigensoftening algorithm, ...
Simulation of granular flows with the material point method
(UniandesMaestría en Ingeniería CivilFacultad de IngenieríaDepartamento de Ingeniería Civil y Ambiental, 2018)
El objetivo principal de esta tesis es investigar la distribución y continuidad de la presión y las partículas de flujos transicionales granulares usando Material Point Method (MPM). Ademas, el papel de la fase liquida en ...

Numerical modelling of Alto Verde landslide using the material point method
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-11-01)
A huge landslide took place at Alto Verde residential complex at the end of 2008 in the city of Medellin, Colombia, claiming the lives of twelve people and destroying six houses. Landslides are characterized by large ...
Concentration of constitutional and thermal defects in UAl4
(Elsevier Science, 2016-09)
The point defect structure of intermetallic compound oI20 UAl4 is investigated using a combination of the statistical mechanical Wagner–Schottky model and first-principles calculations within a projector augmented wave ...
