Previous studies have shown that the multi-cell bi-tubular tubes exhibit superior energy
absorption compared to the multi-cell tubes. To further improve the energy absorption of the …

This research investigates the energy absorption capability of a new bio-inspired cylindrical
sandwich structure (BCSS). The sandwich core of the BCSS is designed to mimic the …

Biological structures optimized through natural selection provide valuable insights for
engineering load-bearing components. This paper reviews six key strategies evolved in …

This research proposes a novel bio-inspired bi-directional gradient hierarchical multi-cell
(BGHM) structure for efficient energy absorption. Its dynamic crushing performance and …

This paper introduces a new type of energy-absorbing hierarchical tapered structure,
mimicking the hierarchical architecture of barnacle. The proposed structures are designed …

Honeycomb structures are commonly adopted due to their superior energy absorption
capacity. In this study, a new bionic glass sponge–type honeycomb structure (BSH) with a …

The penetration fuze, as the initiation control component of the penetration weapon, usually
experiences an overload of tens of thousands or even hundreds of thousands of g during the …

Inspired by the cross-sectional structure and transverse diaphragm of horsetail stem, six
types of bionic bumper structures are designed and their crashworthiness performances are …

Thin-walled tubes are widely used as energy absorbers to increase the crash resistance and
safety while maintaining lightness. There has been an increase in interest in the integration …

In this paper, we focus on the design of multi-cell hexagonal tubes filled with self-similar
inspired multi-cell tubes with a different layout. The effect of the hierarchy design, layout …
