Starting from the development that has reached the computational means in the last decades, the application of the numeric methods in the simulation of the interaction soil tillage-tool, has won in acceptance. Taking into account, the objective of this present work is to simulate the soil mechanical behavior in the soil-tillage tool interface by means of the finite element method. Starting from the employment of a model that is based on frictional approaches, with the inclusion of the adherence and the establishment of a tension of slip limit, as penalty to restrict the relative displacement between both surfaces. The models were implemented in the computational tool ABAQUS 6.4, starting from that which the soil-metal relative displacement was simulated. The results evidenced the validity of the model implemented to simulate the soil mechanical response in the soil-tool interface. The errors in the prediction of the soil stress oscillated from 1.45% to 5.45%, for the case of the soil vertical deformations it varied among 2.22% to 3.57%.
