Integral foam has been used in the production of polymer materials for a long time. Metal
integral foam casting systems are obtained by transferring and adapting polymer injection …

Direct impact testing with a Hopkinson bar is, nowadays, a very popular experimental
technique for investigating the behavior of cellular materials, eg, lattice metamaterials, at …

Considering the lack of abundant experimental data on metal foams under tensile triaxial
loadings, characterization of the yield surface of metallic foam is controversial. In this paper …

The uniaxial compressive mechanical properties of PVC foams considering the effects of
density (ρ= 60− 200 kg/m 3), strain rate (ε˙= 0.001− 721/s) and anisotropy (R= 1− 1.57) have …

In this paper, impact testing of auxetic structures filled with strain rate sensitive material is
presented. Two dimensional missing rib, 2D re‐entrant honeycomb, and 3D re‐entrant …

Abstract 3D image-based finite element (FE) modelling provides the feasibility to explore
how the subtle structural features inside metallic foams affect their complex deformation and …

This study presents an efficient approach to generate a realistic micromechanical model for
closed-cell foams using irregular Voronoi models. Starting with a reference microstructure …

A novel path independent digital volume correlation (DVC) method is proposed, in which the
internal deformation field is determined with the aid of the features extracted from the volume …

Failure surfaces of foam materials in the principal-stress/strain space are quite different from
those of dense materials. They cannot be deduced directly by several simple tests such as …

This paper experimentally and numerically investigates the free vibration, quasi-static
compressive and split Hopkinson pressure bar impact responses of hybrid composite …
