Abstract


In the presence of two bodies, interface effects may play an important role. The inclusion of contact-friction in the model can be a useful approach. This is the case for example of recent depot on a former layer. The practical applications are in geology or geodynamics, also in the stability analysis of artificial embankments, and in the modeling of waste storages. In this paper, we study a slope subject of failure. In stability analysis, we use interaction of contact friction between two blocks (bodies). This study was carried out by the finite element method coupled with the shear strength reduction technique. Results of this study show that must take in consideration any rupture in slopes, because this help us to know the real situation after analysis the slope. In addition, the importance of the presence interaction interfaces in modeling frictional contact between soil interfaces, the interface Young's modulus plays a very important role in the interaction.
