Numerical simulation of hillside mine waste dump construction

Abstract: ResumoNas atividades que envolvem armazenamento de estéril de mineração é necessá-ria, a realização de um estudo prévio do comportamento mecânico, tanto das pilhas de estéril, quanto do terreno de fundação. Face à complexidade relacionada a esse tipo de problema, a utilização de técnicas numéricas é indispensável, ainda que forneçam uma resposta aproximada para o problema. Desta forma, apresentam-se, nesse trabalho, os resultados de uma análise tensão-deformação-resistência com base no método dos elementos fin… Show more

“…At each construction stage, the group of elements to be built has the status changed to "turn on" (resulting in the release of their respective degrees of freedom). Hence, the "turn on," or active, elements are allowed to contribute to the overall stiffness of the system (Teixeira, 2012).…”

“…The equilibrium equations of a mechanical problem, in static condition, describe a non-linear equation system when adopting an elasto-plastic stress-strain-strength relationship (Teixeira et al 2012). During a given equilibrium path, the variation on the displacement, strain, and stress fields depends on the stress and strain levels and their history through the equilibrium path.…”
