Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …

Polyurea has attracted extensive attention from researchers and engineers in the field of
blast and impact protection due to its excellent quasi-static mechanical properties and …

Protecting building, critical infrastructure and military vehicles from Improvised Explosive
Devices (IEDs) has become a critical task. This study aims to examine the performance of a …

In this paper, a sandwich panel composed of two metal face sheets and a three-dimensional
(3D) isotropic foam core with negative Poisson's ratio (NPR) was established via FEM. The …

Auxetic double arrowhead honeycombs (DAHs) featured by negative Poisson's ratio is
attracting increasing attention owing to their tailorable mechanical properties and …

This review outlines the evolution of sandwich panels based on recent work and older
sources, focusing on the trends concerning sandwich panel achievements and applications …

In this paper, field blast tests and numerical simulations were conducted to investigate the
strengthening effect of polyurea on the blast resistance of the normal reinforced concrete …

Experiments have shown that the ballistic performance of the steel plate improves
significantly after coating polyurea at the impact face. However, the strengthening …

Auxetic honeycomb structures have drawn increasing attention for impact/blast protection
purposes owing to their superior indentation resistance and energy absorption capability …

Pure polyurea (PU) coating has hidden danger in covering blast fragments and reducing
structural local damage when blast-induced perforation occurs in the structure. Thus …
