A limitation … WebBoth normal and tangential forces have damping components where the damping coefficient is related to the coefficient of restitution as described in (Tsuji, Tanaka and Ishida 1992). The tangential friction force follows the Coulomb law of friction model as in, for example, (Cundall and Strack 1979).
