Abstract Impact phenomenon is a complicated mechanical problems frequently encountered in our daily life,
especially in the military field. Numerical manifold method (NMM) is a novel numerical theory which is
proposed based on dual-topology to solve the continuous-discontinues displacement field in both static and
dynamic mechanical problems. In the present work, the 3D-NMM program framework enriched with the
cover-based contact theory is developed to simulate the impact mechanical problems. Classic Taylor rod
experiments with different length-diameter ratios and hitting velocities (150-250m/s) are systematic
conducted with ourselves code. The simulation shows that as the impact speed increasing, More >
