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, the plastic
deformation of the rod gradually increased, and there is also a significant upsetting of the impact end.
Otherwise, by comparing the results of NMM with FEM, it is observed that the deformation field of NMM
result are in great agreement with FEM’s within the allowable error range. The present study successfully
verified that our 3D-NMM is suitable for solving structural deformation and dynamic impact problems,
which shows a very broad application prospect and research value in the field of continuous-discontinuous
structural mechanics.
