1. Estudo de mecanismos de deformação lenta da gipsita bandada da Chapada do Araripe em ensaios de fluência monitorados por emissão acústica / Study of slow deformation mechanisms of the banded gypsum rock of the Chapada do Araripe in creep tests monitored by acoustic emission
Experimental studies by several authors have shown some of the key deformation mechanisms in gypsum, such as plastic flow and pressure dissolution. Even so, there is still sparse knowledge about the mechanical behavior of natural gypsum rocks. Creep mechanisms of the banded gypsum rock of Santana Formation from the Chapada do Araripe (Santana Formation) in c

2. Time-dependent behavior of sulphatic rocks of the anhydrite and gypsum / Comportamento dependente do tempo de rochas sulfáticas de anidrita e gipso
The purpose of this thesis is to contribute for the knowledge of time-dependent behavior of sulfatic rocks of anhydrite and gypsum. Emphasis is given to provide straightforward arguments about physical mechanisms responsible for creep observed in some underground excavations in those rocks in Europe. Explanation for this phenomena is not clear yet and studie
