Understanding the mechanical response of structures such as plates and thin-walled
extrusions subjected to cutting and tearing by hardened wedges (blades) is of great interest …

Abstract Design of multi-cell sectional configuration has been considered an effective way to
enhance the crashworthiness performance of metallic thin-walled structure. Nevertheless, it …

This paper proposes a new type of combined splitting circular tube energy absorber for
subway vehicles. An impact experiment is conducted to investigate the dynamic crushing …

Selective laser melting (SLM) is a mature method in the fabrication of structures bearing
static loading and small strains; however, structures experiencing large deformation under …

This paper presents an investigation into the energy absorption behaviour of splitting
multiple circular tubes by theoretical, experimental and numerical methods. A theoretical …

To explore the influence of path deflection on crack propagation, a path planning algorithm
is presented to calculate the crack growth length. The fatigue crack growth life of metal …

In this study, the theoretical model of the expansion metal tubes reported in [1] is improved
by considering the die radius r die. After the critical die radius r die* decided by the tube …
