Following nature's design principles, biological entities have evolved to be highly efficient
and multifunctional to maximize all the available materials and structures and to survive in …

It is widely known that the demand for lightweight structures with excellent energy absorption
capacity is paramount in numerous engineering applications. Many publications have …

This study proposed a new bio-inspired hierarchical circular honeycomb (BHCH), mimicking
the hierarchical structures from wood. The mechanical properties and energy absorption …

This study proposes novel bio-inspired fractal multi-cell circular (BFMC) tubes for energy
absorption. The inner structures of the proposed BFMC tubes were constructed based on the …

The ability of a vehicle to protect its occupants from serious injuries in the event of a collision
is defined as crashworthiness. The proper design of lightweight energy absorption …

Nature has a wide range of biological protection strategies that show resilience to impact
loading. These strategies also serve a certain amount of flexibility that contribute to body …

Origami structures are commonly constructed by folding a two-dimensional sheet according
to a given crease pattern. The existence of abundant crease patterns means that many three …

In order to improve the crashworthiness and energy absorption of thin-walled tubes, this
work proposes a novel design inspired by the vascular fiber sheath flap (VF) and central …

Ceramics are attractive for structural components because of their excellent load-bearing
capacity. Nevertheless, inferior energy-absorbing ability and poor reliability under common …

In this paper, an innovative bio-inspired multi-layered graded foam-filled structure (MGFS)
mimicking the characteristics of the human skeleton was proposed in an attempt to improve …
