Abstract

A numerical simulation based on FEM is used to study the influence of impact velocity on the crushing behavior of circular tubes when subjected to an axial impact. It is found thai the first peak stress during an impact becomes higher with increase of impact velocity due to the inertia effects of radial direction. An empirical equation is proposed to evaluate the first peak stress. Also, il is found that the effect of impact velocity on the first peak stress depends on the strain hardening ratio Eh/E and the tube thickness-to radius ratio t/R.
