In this paper, a theoretical expression for the mean crushing force F avg and the analysis of
specific energy absorption (SEA) ratios of five different multi-cell square tubes were derived …

Crushing behavior of multi-cell tubes with a novel pattern of design for their cross-section is
investigated under axial and oblique loads. The tubes have hexagonal, octagonal and …

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 …

This paper presents experimental and numerical investigations of a new type of combined
energy absorber which working on the principle of expanding and splitting of the circular …

To satisfy the requirements for passive safety protection during railway vehicle collisions, a
front-end energy absorbing structure for a certain railway vehicle was designed with its …

This paper presents an experimental investigation of a new type of energy absorber that
works on the principle of active–passive integration. The absorber consists of a crush tube …

This paper presents an investigation on the energy absorption behavior of shrink circular
tube under quasi-static loading by experimental and numerical methods. The circular tube is …

The energy absorption responses of conventional tubes and tubes with diaphragms are
analysed here by means of finite element simulation. Numerical results show that tubes with …

In order to minimize injuries and protect safety of seated occupants in train collision, this
study proposed a self-protective posture with hands laced behind head and body curled up …

Expansion tubes have been considered to be promising impact-resistant structures due to
their lightweight and high specific energy absorption capacity. The mechanical behaviors of …
