1. Coupled numerical simulation of a tailings deposit by FEM
Abstract Researchers have found that a valuable alternative for predicting the mechanical behavior of landfill construction is numerical simulation based on the finite element method. The results of such a numerical simulation for a sandy tailings deposit from the iron mining coupling flow and deformation are presented herein. This study investigates the inf

2. ImplementaÃÃo em elementos finitos das equaÃÃes de pressÃo e saturaÃÃo para simulaÃÃo de fluxo bifÃsico em reservatÃrios de petrÃleo deformÃveis
A injeÃÃo e extraÃÃo de fluidos de um reservatÃrio de petrÃleo causam variaÃÃes de pressÃes, temperatura e saturaÃÃes, que podem afetar o estado de tensÃes, levando a deformaÃÃes na rocha reservatÃrio e modificando sua porosidade e permeabilidade, bem como afeta as rochas vizinhas. Trata-se, portanto, de um problema acoplado onde o fluxo de fl

3. WEATHER-RELATED GEO-HAZARD ASSESSMENT MODEL FOR RAILWAY EMBANKMENT STABILITY
The primary objective of this thesis is to develop a model for quantification of weather-related railway embankments hazards. The model for quantification of embankment hazards constitutes an essential component of a decision support system that is required for the management of railway embankment hazards. A model for the deterministic and probabilistic asse

4. Modelagem acoplada hidro-mecÃnica da perfuraÃÃo de poÃos em rochas frÃgeis
The thesis presents the first results of a research theme that is now going on the Civil Engineering Department of the Federal University of Pernambuco, which deals with wellbore stability in brittle rocks. The aim is to implement in a finite element code which solves simultaneously the stress equilibrium and the mass balance equation of pore fluid more real
