Abstract
Flow behavior of the driven two-dimensional vortex lattice is numerically s tudied with different densities of randomly distributed pointlike pinning c enters. Different features in the curves of velocity-force dependence are f ound between the elastic and plastic regimes. Scaling fit between force and velocity above the critical driving force can be obtained in the elastic r egime but fails in the plastic regime. Transition from the elastic to plast ic regimes is accompanied by maximum peaks in the differential curves of ve locity-force dependence in the disordered vortex lattice.
