Energy absorption in expanding metallic wire mesh tubes Open
The deformation process and energy absorption of metal wire mesh tubes under quasi-static expanding by a hemispherical-cylindrical indenter were investigated by experimental tests, finite element (FE) simulations and analytical modelling. …

Quasi-static three-point bending of sandwich panels with Miura-ori cores Open
Collapse mechanisms of sandwich panels with Miura-ori cores are analysed and classification of the deformation regimes under three-point bending is proposed. It is revealed that the homogenisation approach to the core material properties i…

Analytical and finite element analyses on axial tensile behaviour of origami bellows with polygonal cross-section Open
The mechanical behaviour and energy absorption (EA) of origami bellows with polygonal cross-sections under quasi-static axial tension were numerically and theoretically investigated. The finite element analysis results showed that the plat…

The Compressive and Shear Characteristics of Miura-ori Forms as Core Materials of Sandwich Structures Open
The mechanical properties of Miura-ori foldcore metamaterials were studied using finite element simulations. The responses of foldcores with various topological parameters to quasi-static out-of-plane compression and shear loading were ana…

Primary and Reflected Compaction Waves in a Foam Rod Due to an Axial Impact by a Small Mass Open
The propagation of compaction waves in a stationary foam block subjected to an impact by a small mass is studied in order to examine the mechanism of compaction within the primary and reflected stress waves. The analysis is focused on alum…
