In this work, the bipenalty approach was applied in the isogeometric NURBS based variant of our symmetry preserving explicit finite element contact-impact algorithm. Several numerical examples were presented including the impact of two tubes and the longitudinal impact of two thick plates, for which an analytical solution was available. In all cases the superiority of the bipenalty method over the standard penalty method was demonstrated.
