Abstract: | We present a time-stepping method to simulate rigid multibody dynamics with inelastic collision, contact, and friction. The
method progresses with fixed time step without backtracking for collision and solves at every step a strictly convex quadratic
program. We prove that a solution sequence of the method converges to the solution of a measure differential inclusion. We
present numerical results for a few examples, and we illustrate the difference between the results from our scheme and previous,
linear-complementarity-based time-stepping schemes. |
