In the context of dam engineering, one topic of great interest is the behavior of mine tailings. In Brazil, a high productivity mining country, the concern about mine tailings behavior increased after recent dam failures. One way to study the strength of these materials is through laboratory tests, specially the Simple Shear tests, which allow to perform analysis by the hypothesis of plane strain. This paper aims to reproduce the behavior of mine tailings when subjected to Simple Shear tests through numerical simulation using the student version of Abaqus®. The analysis performed considered a modified CamClay material and the results were compared to those obtained by Gonçalves (2021), for effective confining stresses of 50 and 100 kPa. The numerical model could reproduce fundamental soil behavior, showing good agreement and converging to the mean confining effective stress.
