An orthotropic interface damage model for simulating drying processes in soils
(2018-10-01)
The study of drying process in soils has received an increased attention in the last few years. This is very complex phenomenon that generally leads to the formation and propagation of desiccation cracks in the soil mass. ...
Estudo numérico da estabilidade elástica de placas de aço enrijecidas utilizando a geometria clothoidal como enrijecedor
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASPrograma de Pós-Graduação em Engenharia de EstruturasUFMG, 2021-12-02)
The use of elements characterized as slender steel plates is common in the structural design of civil construction projects, justified by their high mechanical strength, weight reduction and efficient material consumption. ...

Modelling and simulation of microfluidic chips for analytical aplications
(2011-03-01)
Lab-on-a-Chips (LOC) are microdevices that integrate one or several laboratory functions on a single chip of a few square centimeters. LOC provide a platform to conduct chemical and biochemical analysis in a wide variety ...
Implementação computacional de elementos de interface com elevada razão de aspecto para análise não linear de estruturas de concreto
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA ESTRUTURASPrograma de Pós-Graduação em Engenharia de EstruturasUFMG, 2019-05-24)
A finite element model is implemented and applied for nonlinear analysis of quasi brittle media in order to describe the behavior of the media even after the crack opening. The issue of degradation is dealt with formulations ...
Modelling fracture formation and propagation in geo-materials
(2019-06-25)
The modelling of fracture formation and propagation in geo-materials is a subject of interest in several problems and applications. In this work, finite elements with high aspect ratio are used to study the hydraulic ...
Synthetic benchmark for the computation of equivalent properties in coupled flow and geomechanics conditions for a fractured carbonate rock
(2018-01-01)
In this work, we report on a successful benchmark program motivated by the development of robust hydro-mechanical coupled models capable of providing accurate equivalent properties, such as permeability and porosity, in ...
