Honeycombs are ultra-light materials with outstanding mechanical properties, which mainly
originate from their unit cell configurations rather than the properties of matrix materials …

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 …

This paper presents an analytical framework with a bottom-up multi-step approach to predict
the in-plane mechanical properties including the effective Young's modulus and Poisson's …

The current study introduces a novel class of bio-inspired and 3D-printed metastructures
called functionally graded lattice metamaterial beams (FGLBs). These lightweight lattice …

Compared to traditional materials, auxetic materials possess superior bending resistance
and energy absorption properties due to their special deformation mechanism. To take …

Lightweight lattice metamaterials can effectively enhance the impact resistance of thin-
walled structures. With the aim of further investigating the potential of lattice-filled composite …

Hierarchical structures and gradient structures have become research hotspots due to their
excellent crashworthiness. However, hierarchical gradient structures that combine …

Lightweight auxetic reentrant honeycombs (ARH) with negative Poisson's ratio (NPR) are
very promising for crashworthiness applications due to high specific-strength and energy …
