Opis:: The paper presents implementation of a viscoelastic boundary condition to Yade software. The implemented boundary condition constraints linear displacements of bodies by applying a reaction force resulting from a solution of the Burgers rheologicalmodel. This work presents the results of one of validation tests, where the output of Discrete Element Simulation (DEM) was compared with an analytically formulated soft-contact problem. Furthermore, potential application in more complex simulations (plate load test) is demonstrated. It shows that the proposed approach allows for realistic yet efficient modeling of foundations purely within the DEM framework.

Opis:: We consider dynamic problems which describe frictional contact between a body and a foundation. The constitutive law is viscoelastic or elastic and the frictional contact is modelled by a general subdifferential condition on the velocity, including the normal damped responses. We derive weak formulations for the models and prove existence and uniqueness results. The proofs are based on the theory of second-order evolution variational inequalities. We show that the solutions of the viscoelastic problems converge to the solution of the corresponding elastic problem as the viscosity tensor tends to zero and when the frictional potential function converges to the corresponding function in the elastic problem
